I am very much into this topic because there is a lot to say about it, see, it's always about the mindset, if yours plays the trick on you it's over, why do people feel hesitant when it's time to buy Bitcoin? Why do people find it hard to accumulate Bitcoin? You think it's always about the lack of money?
Now, back to gambling, there are things we do in our daily lives that makes no sense, or let me say in the lives of poor people, they don't have money to lose, accepted, but they have the money to use of alcohol drinks, they have the money to waste on friends that wish them no good in life, they have the money to carry prostitutes.
The best advice is use the money you can afford to lose, it's the same money you can afford to spend on drinks, throw a party, buy unnecessary things.
Yes I have the money I can afford to lose, that's why I made it this far, I avoid getting broke because I use what I can afford to lose and I also take risks to change my life and it's working because I can withstand losing some dollars.
