Topic: How Do You Convince Someone On Something That Will Not Work (Read 239 times)

Well I just convinced him to slow down after experiencing losses in the early rounds and showing the many articles that martingale would not work, he gave his bonus to his and just allocated a small portion to gamble and promised that he would not spend a lot of times to gamble, I don't know if he can keep his promises but he can do research on his own and decides if he wants to pursue gambling, locking this thread now.

There are people that don't have a strong mental construct to deal with situation of financial joy specially the one that occurred spontaneously with gamble he never expected but out of a first time trial it just happened. Before you know it they get absorbed by the delusion that by increasing their wagering they are going to get a bigger chance of winning big amount.

When we having a conversation with people for the first time or people that it has been long we last saw, we shouldn't introduce gambling in the discussion no matter how interesting the conversation gets, as we don't know what circumstance and situation that person has been facing and probably have been cracking his head to think of something to fetch him money, and now you have brought one up, gambling, and behind you he gave it a test and it was in his favour and you expect him to listen to any advise you have to say to talk him down from continuing.... Hell no.
It would have been better you never chip in the discuss  when you both first met.

This is a case of getting addicted to winning because of beginner's luck, your friend is just too excited for a chance to make money from an old trick that kept victimizing newbies, I don't think even a good explanation will discourage him from going with his plan, so just guide him and monitor him and let him find out about the truth in gambling, it will hurt but he will learn the facts and the facts will guide him on his next moves if he wants to proceed or give up.
We all have an episode like this, it is just unfortunate that your friend will find it out in the early days of his gambling days.

It's not bad to give him a reminder; as long as you just tell him that the risk and method you mentioned, if any, are not really effective, that's all. Now, if he continues what he's doing, let him go.

At least you gave him a warning, and he can't blame you in the end if he loses a lot of money in the martingale. Maybe that friend of yours is a rich person. Because you know that the martingale requires you to have a lot of funds to win really big in gambling, and this is often done in dice games, and I don't know in other games, maybe in slots.

At some points, an outdated methodological system of an experienced gambler has the gamble some reliable tendencies to take winning in the gamble.
In gambling, plus and minus in a calculative logic is a good one.
First you should consider is if it has been favouring him because I don't see any form of our gone logics in gambling unless the organization or system is entirely dissolve or there are some probabilities of gambling skills and and prediction processes that are changed entirely in the system.
But if you found out your that of your friend is totally at the wrong side and obvious to you, you can talk to him about him not like one of arguement but a discussion.

You you want to take it indirectly personal to convince him, you can have yourself and some other person's for instance whom had been doomed at the cost of taking such measures of his because if he losts, your conscience should have you to be blamed but after your endivoirs to air your feeling's towards him out and he still fails you are conscience free.
Friends indeed are friends in need. Always do your best as you can.

You can advise him not to bet with big money because it will give him a bigger risk too. If he loses at gambling, he will definitely lose a large amount of money that he may not be able to deal with, especially if the money is for his vacation. He will probably lose the money to pay for his vacation because he has lost from gambling.

Yes, we should not discuss gambling when we are talking to other people, especially if they are old friends whom we rarely see. We don't know what developments they are getting so we have to be careful not to discuss gambling issues with just anyone.

the best experience is simply feeling one's own mistakes.
I mean, maybe you dont need to discourage him by telling him that martingale will make him fail because it seems like your friend is too enthusiastic and is sure that he will use the martingale strategy successfully for gambling and on the other hand, your friend is too excited and is sure that the strategy will be successful in your efforts telling him about the failure of the strategy would only be in vain because he was already influenced by self confidence.

so its better for you to let him do what he wants to do and you just have to look at it. If it works, consider him lucky, but if he fails and loses his money, you can tell him all about the bad effects of the Martingale, which he will listen to well, even in the future.

the best method is to try to explain what are the advantages and risks of such a choice.
perhaps show other people's experiences, basic calculations, in short, clearly show the reality of the situation.

it's really hard to convince anyone.
In such cases, everyone believes they have found the deal of a lifetime even if every logical sign says otherwise! (If something seems to good to be true...)

As a friend, what you need to do is make things clear. Then let others decide. You can't force anyone...

Totally cannot be stopped and they would really be pursuing things on what they do have in mind and this would really be a normal approach because on the time that you are winning then you would be normally think that it would be lasting for a while and as a human being then it would really be that normal that you will really be that activating that greed which its normal. Some can control it and some cant.
This is why we do see different conditions on particular gamblers on which there are ones who do able to control themselves and there are ones who do end up getting wrecked and totally lost up big
time with their money and the winnings that they had gained which it would be given back into the house and you would really be telling int yourself that you should have stopped completely
but well its already too late.

Just like on what others been saying it would be better that you should really be letting him be on what are the actions that he would be making.
You wont really be able to learn up something if you wont really be able to experience it for yourself.

It is really hard for us to tell someone to stop, knowing that some strategy works for them in gambling. If your friend suffers successive loss I think that was the perfect time to discourage him or her that there is no working strategy in gambling that keeps you winning. You just need a timing when doing this because one wrong move could end your friendship if that guy is not having your advice.

Exactly, because a gamblers that is in the momentum of winning cannot be stopped, imagine saying it directly to him and he is in the momentum of winning, I don't think he will be happy with it, because as long as it benefits him he will not stop that so called "Martingale" method he is using, and as long as he is winning I don't think think that you should stop him, let him learn his own lesson, if you are really concern then let him realize the cause of what is doing, your role only is to give advise if the method he is using fails and cost him too much, and I don't think he will listen to you right away, I'm sure he will keep on playing in the same way until he don't realise that he lose all he has. So you are just there to guide and advise, but you never have the responsibility to stop him; it's his only life. Let him know the bitter end if it comes.

Don't try to stop him on what he do since if he is a close minded individual for sure he will not appreciate your advice but instead he feel bad about it and think about you are stopping him to earn a lot of money or worse he will just think about you are just jealous because he know something while you don't know anything.

So try to stay at current rate and just let him what he want to do then once he lost then try to give your words about the mistakes he do since for sure by that time he would provably listen since experience is best teacher and he would provably consider that huge lose and take your words seriously.

There is no need to discourage him, just remind him that not everyday is a sunny day.  He might find his luck on his first gameplay but luck may not be of his the next time he play.  I believe he is old enough to decide things and weigh the situation and adjust his gameplay.  Discouraging him may bring your conversation to an argument so much better to have a light approach by simply reminding the person.  If he don't head your reminders then it is all his fault, and he can't blame you because you already told him of the possibilities.


There is nothing wrong talking about online gambling to newbies, what is wrong is hyping them to engage in such activities.

First of all, discuss him about his gambling habits. Ask if he is a frequent gambler or if he gambles purely for entertainment as the answer will depend on the method you will be using. Second, after knowing such information, you can at least recommend him another method of gambling which is less-risky compared to the Martingale strategy. Lastly, if he still wants to use this strategy, then let him be. Convincing someone into changing something that they have been used into doing so will be futile as they are already decided with their strategy.

Though this may be the case, the determining factor here is his goal on why he gambles- does he gamble for profit; or for entertainment?

If he gambles for profit, then I would definitely try my best to suggest to him other methods in order to at least guide him in the process. Whereas if he gambles for entertainment, then let him play whatever strategy he desires.

You said that your friend has been successful with his run with that Martingale strategy which means that even if you try to convince him, you'll probably going to fail because he's got a bias that it's effective to him and that he might argue that he might be an exception to the rule, have you seen it for yourself OP? That your friend is winning a lot of money because if not then there's the possibility that he's lying because if I win something big like tripling my bankroll, I would probably screenshot that to capture the moment right? But that lying part is just a possibility, I don't think that it's your duty to convince that friend to stop them from doing something that's worked for them anyways, I say that let him find out the hard way.

Yes, its not really that bad to give out some warning specially if he's your bestfriend or close one, as an experienced gambler then you do already know on what are the things that could possibly happen specially it is really just that common sense that we cant really be that able to have those winning permanently specially on gambling. Yes, you might be able to experience those wins on using martingale but it is really just that temporal and something doesnt really last long.If he wont listen then its up to him but at least you have told him something on which he cant blame you
out and would really be feeling sorry on the time that he would be experiencing those problems specially with gambling losses on which it is really that common.

Warn him. I think that's the best you could do.
When your friend entered the world of gambling, I hope he knew the risk that he was taking by doing so. Because there are individuals who heard about one popular casino, and signed up but had no idea what they were doing.
Then the one thing that mostly happens after the sign-up is the trap. He is now living it. It's not beginner's luck but these are baits to make people play more. He will definitely win while he is a non-VIP, I could tell because I've been there, withdrawn a lot of times from my winnings, but now that I am a VIP, I cannot seem to find that same luck that I had before, whatever the strategy I make especially with the casino games and the originals.
"Martingale is for people with deep pockets." That's what I would tell to my friend who is on his way to using that kind of strategy.

The did has been done already no time for the regrets about telling him or not telling, as a good friend you have giving him the advise he needs to get as a grown he has to use his own sense to know when to stop should he start having a bad gamble results. Martingale gambling style isn't a method I will wanna recommend to any gambler the hopes that it raises in an individual is such that you keep believing you will recover by just having a single win which then makes you to comfortably doubling you bets on each one you have lost. I think you should allow him do his thing, he will learn faster through a personal experience and not videos or articles can save him at this junction.

If I were you, I would not stop him outright but rather just give him a fair warning that again, this is gambling with no certainty of success. There are a lot of factors at play, most of which aren't in his control nor favor. Let him realize that there are no guarantees of him making his money back ever again, without stressing the fact that you're trying to stop him. It's his money anyway, so he can do what he wants with it, but as a friend, we have to give advices sometimes that hopefully sways them the other way.

Either way, you will not be accountable for whatever happens to his money. You just had a conversation about gambling, and he himself pursued the idea and made it a reality, and doubled down on that, even.

Just give him a warning and that will do and you did your job as a friend for giving him the reminder and warning that he shouldn't go that much because martingale's known for that effect and result.

Regardless of the result and if he's going to listen to you or not, you're done there and you did your part for telling what you know about the potential result of it.

So, whether he ends well then that's good but if he ends badly, you are at no fault with that and you shouldn't feel any regret because it's not you that moved and gambled the money but him.

The online gambling based on the bitcoin will be the length topic and it had huge things to discuss.After the growth of cryptocurrency,it also had their own growth to the gambling site.Now the bitcoin market had their own demand due to the bull market now,So the same will be reflected in the bitcoin based gambling sites.The gambling site based on cryptocurrency also involves of money laundering,only few gambling sites which I mean.So the gamblers should accept the gambling site which ask them to do kyc for the transaction.So most probably the gambling sites based on the kyc may be the trusted one.

The thing is, Martingale strat does work, but for it to work, you have to have enough money/bankroll to cover your ass up. If you don't, then you're just wasting money.

I think one of the reasons why people don't think the Martingale Strategy doesn't work is because we have the tendency to play more even when we already got what we wanted, which in most cases mean we won our keep, probably earned just as much money as you would need to win back your losses and a few more, and yet some people still find the reason to play despite the fact. Which I say, is stupid first and foremost, and certainly shouldn't be the mentally you possess when you're using the Martingale strategy. because with martingale, you have to stop soon as you get that win, no matter what.

I would love to say you finish what you've started but it's of no use and I don't think the person will change just yet when he thinks he knows the strategy, I believe the person is not a kid so he also know the consequences attach to gambling, even if he has never played bet before he knows the system, sometimes he wants to play but he just what someone to lead him, some people will never involve in gambling even if they have heard it from their friends they still don't give a damn while some would love to gamble and any little speech talking about gamble they will just get involved
You trying to help your friend sounds good but he will not take your advice so he should learn for himself maybe when he experience how gambling works he might change under probability, depend on the kind of person if he's willing to change or not, lessons will be learnt.

I dont really like on getting blamed whenever he had missed out on making some wins and its true that not everyone would really be sharing up with the same fate with gambling on which we know that there are really
people who are really that lucky when it comes to gambling instead on making use of those casual strategy or doesnt make use of one because luck would be always a great factor for you to make yourself that profitable with gambling. So better clear up his way and just let him on what he would really be planning to do .This is really just that for the sake of friendship, even if you are really that in concern for those potential losses
but since he's really that dedicative and optimistic on making more then just let him be and continue for it to play. Giving some advises might really be ending up on some conflicts and debates.
Better not to make yourself that stressed out on how to make them convinced on stopping gambling and just let those results would do the work because losing is inevitable with
martingale specially when your luck times out.

I understand your plight in trying to save your friend from making a terrible mistake but I think it would be difficult to do so because luck shined in his favor upon his beginning of gambling path. His wins would never allow him forgo the exact strategy as you have mentioned because that was the first mega victory experience he had got through that strategy so telling him to stop is like you taking away food from his mouth and doing that alone would make him feel you do not like the fact that he won through that strategy.

The only thing I think you can advise him to do is to reduce the rate at which he gambles. Also letting him know the consequences of being addicted to gambling and repercussions he may face in the wake up of such. Do well to enlighten him otherwise he would blame you tommorow if his gambling lifestyle becomes a topic of discussion.

He was able to double or triple his bankroll because he was starting with very small bets, otherwise he wouldn't be able to make martingale work.

It sounds good when he brags about it, but in reality he's betting $1 and after a few hours he has $3 and he's happy because he made some money for free. It's funny when you realize how much he's putting on the line to earn a few bucks. Just to earn $1 he needs $2k to feel relatively safe so he can get 10x loss and that's not uncommon so sooner or later he'll lose. I remember trying to martingale years ago and I got 13 L in a row and got liquidated, but that was with a starting bet of a few sats.

Yes you are right, when someone has experienced the joy of gambling, the beauty of playing gambling, and the huge profits in playing gambling. To be able to stop that person from their gambling activities, it is very difficult and when you keep trying to try to stop it, it will be a long debate. Because you and the gambler, both feel the most righteous about this behavior. And sometimes what we are looking for is not the truth, but a justification for our behavior and our arguments.

And back to the original problem, when someone has felt the pleasure of playing gambling, they tend to never realize the risk they face, and when they realize it, they tend to ignore it. Large losses and consecutive defeats, this is not enough to be able to awaken someone from the bad activities he has been doing so far.

Sooner or later on the time that he bust up (hopefully not) but its inevitable specially on the time that he would really be able to experience those nasty consecutive losses on which it would really be
causing that total blown up on your capital and this is something that would really be able to make you realize that it is never been that possible on beating up the house. HOUSE DO ALWAYS WIN in the end
and this is something a very common line that we do know on gambling field specially on going against the house or casino on which it would be normal that these things would really
be that the reality on gambling world.

Just like on what others been people been saying that it would really be just that right that you should really be letting him be on experiencing those things
without the need on telling him on what he should gonna do. People would really be able to find out and realize on whats the real deal
on the time that they would be able to experience.

For me this is just a simple case to handle because I really think that even if you try your best to tell the new gambler about how he can lose in the bet, he will still not agree to you because he has already gotten some huge winning and it is beginning to drow his attentions to deposit money and gamble more.
However, for me, I will say you should let him try it or you tell him to stop but if he in any way refused then you should let him see or try for him self,,, if he win, then we have to thank God for that and if he still lose, we still thank God for that because at that time he must have learnt a lesson that he will live to tell other new gambles too.
Although, it is not a good thing to see a very good friend of yours lose in gamble just because he or she refused to take your advise.
As still, even if you try to discourage him, one day, on your absence he will still try to do same thing you told him not to do.

Everyone is peculiar and will have different experience in gambling. You friend have been winning using Martingale betting strategies and it will be difficult to convince him to change his style. My suggestion is that it you can convince him to change his gambling strategy that will be nice but I doubt if you would be able to achieve it because that is his best option for now. Every gambler is an adult to you will not force them to take any decision. This is because they might blame you if something go wrong.

Just tell him your view about his strategy and allow him to make his decision, after all he I matured and thr money is not yours. As much as he gambles with what he can afford to lose, that will be fine. There are people that will never accept a good advice until the learn from personal experience.

There is nothing wrong in introducing someone to gambling as long as the person is not underaged or a financial dependant. But when you introduce them ensure you give them the right understanding of how gambling works. The should be aware that they have to gamble responsibly and not to become addicts. You should teach them to have a gambling budget and only gamble what they can afford to lose. It's also important to enlighten them about diverse gambling strategies stating clearly the advantages and pitfalls of each strategy. Gambling requires a lifelong learning process, so as newbies keep betting, they will gain more experience.

Well am not surprised at all, as this is the first stage or should I say effect of rush win in gambling, many gambler has gone through this phase before because the excitement of wins in gambling will overshadow your thinking and make you so lose focus on what you tend doing next because at that moment, all what would be playing is how to effectively achieve the same feat on a constant basis which is definitely impossible.

Aslo this phase is when the gambler actually takes no advice because of the wins he had already experience so thinking of advising won't be of any use at all as all his taught is to replicate the exact same scenario that got him that same missing funds.

Well, it did just turn out that your friend was lucky on making use of martingale on which we know that it cant really be that profitable in longer runs. It is really just that he had been get used to be lucky on the time that he made out some gambling on this particular moment on which it is really just that a right call that he made out such gambling session.So the question if you would really be telling him the truth?
It would really be just better that you should let him be on the things that he would really be tending to do because it would really just that make him realize on the time that he would be experiencing some losses.

We do know that there's no such thing about being holy grail when it comes to gambling on which there would really be coming into a point on which you would be thinking that it does exist
until that reality would really be slapping hard into your face and make you realize that this doesnt exist in the first place. People do really need to face up the reality so that they would really be
able to learn on what are the things that realistically happens and not living in world on which they do believe that it could sustain for long.

I think you can work either way but if you still bump with him then tell him the latter approach. The latter may seem difficult but I think it's worth it if you'll pay attention on the details on how to be a good gambler. Martingale is by far one of the risky strategies out there but if luck is on your side you'd likely made some fortunes.

Someone will only believe what they believe, if so far he has been successful in gambling using the Martingale method, whatever you do for him, such as sharing testimonials, articles or whatever, it will not have any effect on him. He will continue to do what he wants to do. IMO, the only thing you can do now is leave it alone until he understands that his method is a bad method in the long run.

This is a really tight situation, as you are left with no better options. You might also be considering what the outcome of the discussion will be with him, what he will see it like, and whether he will not think that you don't want his success, and by so doing, you are trying to talk him out of making more money over the weekend.
 
Then again, you could also be thinking, On the other hand, if you keep quiet and say nothing and he proceeds with his decision and makes the deposit and loses all that money to gambling, will you be happy with yourself knowing about it and you did nothing to change his mindset?
 
The best thing to do is do whatever you can to tell him the risk ahead, even if it takes you to show him videos or online articles. Anything you know might look more convincing; just try as you can. If he doesn't want to listen, you can let go of whatever outcome of the weekend gambling comes for him; it's no longer your business; you have cleared your own mind. To me, that's what matters.

The martingale method is not always effective,  there are high risks of making huge losses if the outcome of two of his gambling results are not equal. And he will keep funding his game until he arrives at a profit. This is not always nice. Since your friend has tasted the sweetness of winning using the martingale strategy already, it will be quite difficult convincing him that he is on the wrong path and this is something to be worried about because he might get himself into a financial mess.

He is your friend, talk to him about the disadvantages of the martingale strategy. It is better you talk to him about it than watch him face the outcome of his gamble. It is now left for him to go on with his new strategy or lay low, at least you wouldn't be feeling guilty if he eventually loses. He is an adult and should take full responsibility for all his decisions and actions.

If I were you, I would not trust the words of the first person I meet unless he shows proof. We all know that the Martingale strategy does not work and one day will lead a gambler to a major loss. If you are really confident in this person and want him to save his money of course you should warn him about the high risks of gambling on the Martingale strategy. Just open his eyes to the fact that each subsequent round is in no way related to the previous one.

I did try to convince one since he was up for blackjack martingale. The man begins to believe he has the luck and he has $5k to blow. I told him it only needs a few losing streaks but if you lose 3 to 5 times you go back to the first unit. This will break the successive losing streak and maybe luck will be on your side again.

Yup I have no patience in convincing someone not to try his martingale adventure as if he discovered it first. We already know it works when it works until it doesn't. But maybe a little tweak for him may work.

Please I’m pleading that you self a brother as well as safe yourself from guilt and since you did the introduction, I would advise that you safe this fellow and let him take a break since his was already fortunate enough to make some huge winnings and he shouldn’t let his greed play tricks on him and so the right thing to do is to take it upon yourself to make sure he doesn’t gamble that money because at some point you might be blamed by your friend.

@op I’m pleading that you should keep what so ever beliefs you have and try attending to your friend because you’re just about watching your fiend ruin his life and I’m sure you already know you’ll be one of the persons he’ll rely on to help him keep his life togther and I’m sure you wouldn’t want to carry such load not in this current  global recession.

Let me share a bit of what I've learned being a financial advisor for close to 20 years now.  Probably like 75% of people on earth are immune to good advice.  People get it stuck in their heads that they are right, despite what so many others (with far more experience are telling them).  Take bitconnect for example.  I tried to help so many to see the light that earning 1% a day was not even remotely possible, yet these people whom mostly had never dreamed of making money so easily get so wrapped up in the thought of financial freedom they ignore all warning signs..or simply don't do much research.

So likely nothing you can say could convince them otherwise.  I hate to be this way, but people of lower intelligence are the ones who often think this way.  A lot more difficult to reason with someone of a lower IQ than one that's higher..typically. 

Best of luck though.

I would not say stop him from what he is about to do but it would be perfect if you gave more insight about it and of course, explaining about the martingale's success is not much will help him to realize that strategy is nothing but a faster way to bust our bankroll.

And importantly, I would talk about the money he wants to deposit, I will insist him not deposit any money that he considers he can't afford to lose and if he is taking the risk then he also has to face the consequences of it.

Some people are convinced by emotion, so telling them that the plan is doomed to fail and will ruin them might help. So ask them what they will do if they lose it all.
Otherwise, what the hell, if they think they can handle the losses. Let them. Their own money, their own issue.

I have had this conversation with many people, explaining to them how illogical it is for there to exist a perfect system that always wins in gambling, how casinos would not exist. But some just don't want to listen. I never had to go to the extremes of telling them that they will be in financial ruin, but if it was for somebody I really appreciated I would make the sacrifice.

Sadly, telling the truth sometimes can have consequences to you, the message bearer, as well..

Why? He is a friend and they can also discuss about it. Friends learn from friends. I do not see anything bad for him to tell his friend before it will be too late. Even if his friend will make profit from it, he should just let him knows that martingale strategy can be dangerous, he should still tell his friend and let them discussion on it. Martingale strategy can be very profitable, but so can the loss be.

Allow him to find it or to see it for himself. This is gambling; martingale might not be working to many people in the long run but there's no guarantee that it also won't on his case. Give him the benefit of the doubt, what if he actually won most of the time with such strategy? Then telling him will make it more negative. Atleast if it won't work well on his case, he'd be the one to realize and learn from it. Allow things to happen. Although I get the point that OP is just concerned of his friend but no one can really determine the future. It won't even be proposed in this industry without any validation from other player and we are just all shooting our shots or playing our chances. I'd be happy if his strategy would work well in the long run.

I think you should do research and take all links to stories of martigale's failures in gambling, you should also show him links to data that prove that gambling is not something to get rich, show your friend that no matter how much If he has managed to achieve some successes so far, this does not mean that the successes will be eternal, you can even tell him to continue putting in little money so that he can see for himself that at the end of the day he will lose everything. He probably won't listen to you, that's something to be expected. So why, even if you predict that he won't listen to you, do you have to show him these links?

The answer is simple: so that when he loses everything, he doesn't blame you for not stopping him, he doesn't accuse you of just standing by and watching him fall into disgrace. and also because you will sleep without remorse and without feeling guilty. you warned him and he didn't listen, when you think that way you will feel light and free from guilt. People don't listen until they fall into disgrace, after regret comes and they start listening and think about changing. Unfortunately, many times they have already fallen into a hole so deep that they cannot get out of it anytime soon. just try your best to warn him of this danger and pray that he listens to you, that's all you can do for him

You're absolutely right, as much as I don't want to do this, I guess I have no option but to be like Caezar, washing my hands for whatever happens to him I will just proceed and give him a warning about the risk of that method and too much gambling and I let him decide for himself he is old enough to decide for himself, sometimes beginner's luck in gambling is a curse because it will heighten your motivation to play more.

Let him find out for himself. Trying to discourage him or talk him out of his plan will strengthen his resolve to want to go further. The irony here is that if it should work out for him the first time, he will do it again and again until he faces a huge loss but if he losses the first time, he'll hang his head in shame and agree that you were right.

If you know the say he intends to execute his plan, be there with him and don't say a word. Maybe your presence will play a small role in discouraging him from overdoing it.

It’s too late already for this guy to be stopped since he already experienced the taste of success on his first try. Martingale is really dangerous but sometimes it works on giving successful run on gambling.

I’m not sure how you can convince him anymore to stop gambling even using other testimonials about how dangerous it is because he already has the successful thoughts on his mind. Maybe your best chance is to convince him to just lower his bankroll because there’s no way to completely stop him. Only the experience of losing will gonna teach them the danger of gambling.

Just let him know when to stop and he should not go for lower than 3 odds for martingale to work.

If I earn $200 weekly for example, I can use 5% to gamble at once and not think about the losses. I can use martingale for casino game with 3 odds.

Like this:
The first time I gamble I can use 2x
If I win or lose, I will continue to gamble

Anytime I lose, I increase it to $3
If I win, I will continue to gamble with $3.
If I will the second time, I will stop gambling for the day.


If I lost the second, I will gamble with $5.
If I win, I stop gambling for that week. If I lose, I stop gambling.

What I do not like about martingale is that it will only make you gamble for just short period of time like less than 10 minutes. To prolong it, he can just continue to use $0.5 to have fun.

Let him know how martingale can be very dangerous.

While strolling in a park I bumped into an old friend with whom I had a conversation about online gambling we had a long conversation some three weeks ago, actually the original topic was about Bitcoin but for some reason I mentioned online gambling using Bitcoin, and that what opened about a lengthy conversation about online gambling using Cryptocurrency.

I didn't know that he signed up for one popular casino that I mentioned he started to play there and had huge success using one of the oldest but ineffective methods which is Martingale, I was just surprised that he had a successful run using a variation of martingale on Dice even mentioning of doubling or tripling his bankroll.
He is about to deposit a huge amount of money next week because the holiday is very near and he just wants to explore his so-called new-found method, which is not new to us.

We all know Martingale will not work in the long run, should I let him find out himself but that will incur a heavy loss in this case. 
Or should I discourage him by showing him videos, articles, and testimonials?

Because of this, I will not talk about online gambling to newbie I could put a guy in big trouble.
