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.
In gambling, it depends upon the game being played whether we need to use skill or the only option in hand is to rely on luck. Dice, slot and roulette are all about luck whereas poker players have tricks up their sleeves that are really helpful in the game.
If we talk about Chinese government, indeed it is a smart one and will never ever let go off of bitcoins.
