You must set a limit on your self or a budget when you gamble...
Setting an amount limit might lead to much more losses.
Example a person have a budget of BTC0.01 that day. It gave him more winnings than losing in the short run so in this point, one will think that luck is on their side. Now the bankroll depleted slowly that they can't feel it already depleting and eventually ended up being busted.
In that case, the person will think to chase the loss because it think that it can repeat the winnings it made because of luck and will wrecked his budget quota for that day. So in here, the amount that loss has a chance to doubled.
Setting an amout as a budget is a good thing...
If that person is greedy enough to gamble all his winning on that day its his problem...
If a person is greedy there wont be any winnings at all if he gamble...
Yes it is really good but..
..the problem here is execution. Setting an amount is good but it can't executed properly because gamblers are gamblers even they are doing it fun.
Suggestions are easy to made. But the receiver will surely have a hard time to do that.
