I'd say that anything with the word gamble in it is not safe. The only safe thing you could do is make sure if you are going to bet, only bet what you can afford to lose, and keep your odds of winning relatively high.
That's true.. gambling is not safe in anyway...There's no way that your bets will be safe..But you can always prolong your stay in the gambling site without emptying your bankroll at early stage...bet small..(boring but you could go longer) stick with the chatroom and chat with other gamblers if you feel like you are in a losing streak...
