The story is from about almost 5 years ago but this is 100% relevant to 2018 or 2019 or many years to come, you can read it here:
In short version, he gambled on Bitcoin, made $500,000 - and lost it all later on, he then continued to gamble in Roulette and other games, and ended up with $50,000 in debt.
This is not only related to Bitcoin or Casino Games - if you think Sports betting is different think twice after reading this:
This person lost over $300,000 within 48 hours, all because of sports betting, he had bets on tennis, basketball, soccer - you name it.
you can never be rich with gambling, and even if you end up being "rich" - you would lose the whole lot in no time ... only the house wins because the house has an edge.
If you are careful with your funds you will end up like that, this will not be the first story you hear nor it will be the last story you will be hearing, i have seen people gambling hundreds of bitcoin in dice sites and winning a lot and then end up loosing everything, it is a kind of addiction and you need special care to overcome these issues, i have had my issues in the past, i have not lost this much amount even if i add cumulatively, but i have lost a fairly huge amount if i added all of my gambling losses in the past ten years, all of the losses came through sports betting, there are people who made millions through gambling, but nothing is certain for a longer period, there are people wagging millions for sports gambling but they will have their losses, overcoming these losses is the biggest hurdle.
