I use satoshibet but I don't think trick maybe luck
Not only luck that gives you a profit you can also gain a profit from thinking a wise decision.. If you gain a profit even its little profit don't rebet to avoid lost..
I think advising for every one to make a wise decision on your exit while gambling is very easy but when you're gambling then it is almost impossible to do it because if your in winning mode then you think today you got a luck so you can make money or if your in losing mode then you want to recover your loses so you will continue until you lose all your money. This is common gambling behavior but some people will exit at right time but at some times only.
