In my opinion, before we continue this conversation, we need to clearly understand that investing is a way to make money (sometimes very risky) and gambling is entertainment. I would advise against making the wrong associations in your head, as some do, and not trying to get rich in a casino, as it depends on luck, not desire, amount of money or free time.
This is correct, that's the difference between investing and gambling. But it's much better to avoid arguing with the gamblers that don't have their minds open.
These types of people will argue with you until the next morning and won't allow you to win any rounds of your debate. So, just oblige what they say and you've got your own point.
It's pointless to have these arguments win by you as you've got nothing to gain, you've a point and they got a point as well that they believe they're correct above everyone else.
You can't win an argument to people who are not open to any opinion of others.
Well, if you know what you're doing, you don't need to make a debate with other people.
Just continue what you think is best for your money, because later on, they will see the results of your effort.
The will soon find out that you still have some of your satoshis, whereas, most of them have lost theirs with their bets.
So who do you think is the real winner? The one with satoshis at the end or the ones who lost it?
So for me, you don't need to win on this argument, just look at the outcome of your activities.
