It's funny how gamble responsibly could mean differently from one gambler to another. That is like saying gamble what you can afford to lose, and you, OP, is betting as high as $20,000. Of course, you can afford to lose that. To somebody else, or perhaps to most of us here, that is already a life-changing amount we wouldn't just risk on a wager.
Anyway, I'm just saying that what gamblers can afford to lose widely differs. It could be $1. It could be $10 or $100 or $1,000. Or it could be $20,000. The point is that the money that a gambler should bet is an extra.
How I wish I could gamble like you, OP!
Obviously, OP is a high roller and I think there’s no wrong with that as long as he only bet his extra money, not his hard-earned money. But it seems he really gamble responsibly because he is also making his fair share of winnings. However, the good thing about him is he never hide from us his previous huge losses, the reason why he also bet big amount so he can recover his losses easily once he got lucky. But for most of us here, make sure that we should only gamble on an amount we can afford to lose, because once we lose in gambling, there’s no way we can easily regain the amount and it takes another luck or chance to win significant winnings.
