There is no safe methods to gamble. If there is one, it would not be called gambling anymore. There are risks involved in every type of gambling.
Its true. People will not gambling,or create any casino for gambling use if its safe for every user. Hard to win, but if you win,you will win a huge payout. Just keep gambling, because we dont know how luck we are. Even you lose,at least you have a try,rather you just keep looking on the other bets.

"at least u have a try"? my friend, that those words are not mean to be used for every situation, and I don't think say sth like that is any good this time. realize the face that gambling is hard to win should lead to stop gambling, not the opposite.
