My tips is try to avoid Gambling. You can try in BTC trading or mining which is much secure than Gambling.
Isnt it trading the same thing as gambling though?
There is no house edge on gambling, so the exchange doesn't make the rules in a way you'll certainly lose in the long rung. Its at least theoretically possible trade and win in the long run, and the exchange wouldn't be sad with that because you would keep trading and paying commissions.
I think trading is more like a poker game, but with players with different $ bets, and not being totally a zero sum game.
