Every win I'll save bitcoin gambling and will use it to gamble again tomorrow. and after my bitcoin collected will be exchanged into the currency of my country
It's nice that you can stop easy after you win, most people (including me) they have still playing until they are satisfied how much they have won if I'm playing gambling I want to double my capital before I cash out it.
And even if you double it, you want more. I know that feel.

this is why casinos are so profitable, I mean most of us are not even satisfied with doubling our money, we try to go further and we lose. Easy money for the casino owners!
Well this is the common mistakes of people. Like for example, a dice game that uses a martingale system. So a person played using that system and be able to recover what he has lost after some losing streak plus the earnings. But people think martingale effect is endless and keep on gambling until such time he lost all his bankroll. And think that the culprit is the martingale system LOL. You could have a self control in order for the Martingale system to work. So if you win already, better to withdraw your fund together with your bankroll, so you wont be tempted to play again that day.
