Topic: RollinCoin - Raffle GREEN line (Read 1433 times)

Hello everyone.  The owner of this site is a Russian guy.  I don't know who is the developer of this site,  I think it is the hackerboss.  

I was appointed by RollinCoin.com to convey messages to their users as their English speaking skill is too low and he requested me to take care of this.  

I have mentioned everywhere else that I am Moderator of this site and my duty is to help players.

But I soon came to know that the owner is scamming people by changing the hash.  I immediately contacted him asking to pay the players their money otherwise I will resign the moderator position and I will tell everyone you really are scamming everyone.  he just ignored my message saying first let's resolve scam issue and then let's take care of it.

This owner has to pay me some btc too. So he has not only cheated his players,  but also his mod too.





Before this. I have requested this owner to pay fearfulcalm  a thousand times.  But he doesn't reply to those at all.



And finally I resigned it  and then too he decided not to pay him

SCAM SITE   

Well, i think mods must moved this thread to scam thread

nice find. here is the scam accusation thread, feel free to post it there, too. cheers

where proof?

I checked and it work.
where changed hash?
I'm not understand..

Warning all

http://webcache.googleusercontent.com/search?q=cache:il60bLKQcbsJ:rollincoin.com/provably_fair_md5.php

Look at hash cached, and compare the hashs, all bets above 0.05 BTC starting from a point have hash changed, after this 0.02 sequence bets, all win bets have hash changed, don't play!, it will be a 100% lose now

Gambling site paying 0.20 bitcoin as payment doesn't mean its not a scam,you dick.I feel like you're the one behind the website with multiple Alt accounts.The question is about provably fair and is proved your site isn't.So stop digging technical shit,no one believes it. I would not advise anyone to put here even 0.001 bitcoins.

if it scam... why paid 0.2btc now??

That last statement isn't true... MD5 is a weak encryption algorithm that can be broken today, and each MD5 string can match with an infinite number of unique non encrypted strings (just like any hashing algorithm, including SHA256).

This description does not match the procedure executed by the site. The string hashed is not HEAD/<26 characters>, it is "win" or "lose", a colon, and the decimal representation in plain text of the secret key. Not sure where you found this text, but it doesn't describe this game.

This site requires that you browse the provably fair page to see the next game hash. If someone else plays, your hash is taken.  Also, those displayed hashes have changed on at least two recorded (and independently verifiable) occasions, rendering the entire "provably" part irrelevant. The site has already been positively identified changing hash listings after a wager is received. View the wayback machine to see that the listed hashes have been changed from the posted hashes.

Even if the system presented were actually fair (it's not), the game itself is not fair because the hashes presented are not always the hashes of the data played against. This is not provably fair - and actually not fair at all, it will change the result of your bet.

Payment does not indicate "not a scam". Ponzi's pay out until they run out of money, but they're just as scammy. I have demonstrated mathematically that the system professed by this site is not only unfair and unreliable but also incorrectly implemented in a manner that can only be qualified as "cheating".

Even if the site pays, if it has to cheat to maintain an edge, it's a scam.

I see he paid!

NO SCAM!

I see md5 hash before bet http://rollincoin.com/provably_fair_md5.php


I found some info:

What's Next Game Hash?


When you play HEAD or TAIL, our system show the winning BEFORE you begin to play, and displays the result on the page in an encrypted way, called Next Game Hash, for example e3d609a53bfe3c59db30813e6a65273a (It means that we had your result before you place your choice).

For each game we generate a randomized key, of 26 characters long, for example 4f68e3a6f93bf4208457634aa7, then we organize the winning face and the key like this: HEAD/4f68e3a6f93bf4208457634aa7 or TAIL/4f68e3a6f93bf4208457634aa7 and we calculate the MD5 hash of this string. In our example, the MD5 hash of TAIL/4f68e3a6f93bf4208457634aa7 is 41799624d9e08e4552843c32aa96fc4b, so the results of the game must be HEAD.

MD5 is a strong encryption algorithm that cannot be broken today and where each MD5 string matches with one unique non encrypted string. You can find MD5 generators here.

Provably fair requires that it be provable. But I can't prove anything because the hash of my game isn't presented to me before I play - and when I do play, I don't have a guarantee that the hash presented will be the hash played against (we have proof-of-alteration on the books).

Furthermore, MD5 is very weak and could be bruteforced. Judging from the recent bet list, someone has already defeated the system.

Hello,

I investigate this provably fair too.

this really provably fair system, because md5 hash pre generated before bet.
so working with md5 hash lot of casinos in the world https://igames365.com/provably-fair  and more
http://csgoblackjack.com/provably-fair

Thus you can easely verify that the game has been provably fair. Simply copy and paste the “secret string” into any online MD5 checker (e.g. Online MD5. http://onlinemd5.com/

Are you fucking kidding me?!!!!!

Since all of us over at LB are laughing about this situation, I went to the trouble to investigate the RollinCoin Provably Fair system myself. I have got to say that this is 100% useless and you would get a better game if you sat behind the computer with a coin and flipped it yourself.

1. There is absolutely no explanation of how it works. The user is left to figure it out himself. Hardly "provable"!
2. After some wrangling, we determined that the formula is MD5(("win"|"lose")+":SecretKey="+secretKey) to generate the hash.
3. The secret key has no bearing on the game result - as far as I can tell, it does nothing.
4. The user's TXID doesn't affect the game result, either - there is literally no data with which to duplicate the result.
5. The results of a game are not provably fair, are not verifiable and the method by which the results are derived is not transparent.

6. Therefore, I conclude that not only is this game not Provably Fair, it is NOT FAIR AT ALL.

The previous post does not represent LuckyBit and is the personal opinion of stingleword. Sometimes this is required when he posts about things that might be work-related, but when not operating in a work capacity.

Really? It has been proved everywhere else that you changed the hash  and you cheated them  You just let your supporters down and its good that it was found out early . RIP rollincoin.

ho don't remove your post about scam, God will punish you! because we no scam and not cheat! Think about it!

Since when people at bitcointalk started having such low level of intelligence ? If you take a second out to read the negative feedback by NlNico it says,


Reference Link : - https://bitcointalksearch.org/topic/rollincoincom-caught-changing-provably-fair-hashes-after-betting-1469732

It would be stupid of you play here.

NOTICE. STOLEN CONTENT. POSSIBLE FRAUD ALERT

This "promotion" is a clear and blatant theft of the LuckyBit Rose Gold Wallet Raffle - even the text has been stolen. This user is sending PMs to any user that participates in a LuckyBit promotion, advertising this. PM advertisements are a violation of Bitcoin Talk's terms of service and this thread has been reported to the administration.

Participate in this promotion at your own risk. This user and site has engaged in questionable behavior including unsolicited advertising, impersonation, and customer scalping.

Careful, OP is a proven and known SCAMMER, see:
https://bitcointalksearch.org/topic/rollincoincom-caught-changing-provably-fair-hashes-after-betting-1469732

There is a virtual certainty that he will not pay you what you are owed - see his main thread for several people asking for what is rightfully theirs.

I expect this site to close any moment now, and OP to delete his profile only to start some other scam. It is sad, really.

i was willing to participate in your contest but then i saw red trust.

thanks for advice sir!

Just some friendly advice. When starting a promotion it's better to come up with something original. Now you blantantly copy/pasted the LuckyBit promotion.

this offer is nice giving new opportunity to win free bitcoin while playing the game goodluck to those bettors that knows how the game works this is another way to win aside from the game itself just needed to play with minimum of .05btc then you can play the raffle good job owner.

Random.org is not provably fair enough in case to draw a raffle like this imho. Because it can be use as many as you want till you get "expected" winner number. Not mention you will do it but you need to use better way in order to draw the winner. Maybe using hash like other raffles. Just my opinion

we will use service
https://www.random.org/

our game with provably fair.

Thanks!

No sir, because good prize

Caxn you lower the minimum bet? I think 0.05 btc is very big.

Since you are still a new site, could you escrow the whole prize? other question, how would you draw the raffle's winners? It should be clear when you make a raffle, because players will always care about the drawing system whether it is provably fair or not.

Oh, nice new raffle.
I want win 0.5btc!

If you have any doubts or issues regarding this raffle . Feel free to contact me or rollincoin.com .
And Sir I think you have made a mistake , it should be
1st prize - 0.5 btc
2nd prize - 0.25  btc
3rd prize - 0.1 btc
Please correct it.

Note: I am MOD , I am here only to help players.
