It all depends on how lucky a person is, but do not expect a permanent profit from gambling as they are entertainment and carry more losses than profits.
Well it doesnt depend all on how lucky a person is. It is how disciplined he is or his knowing on his limits in gambling. Win a little, stop, try again next time.
Lucky is not at all, you have to stay strong too. When you see China is making a ridiculous law about banned Bitcoin but still let Chinese traders can trade bitcoin at Hong Kong , i already knew something happen . Whales are trying to swallow all of us who doesn't have balls.
