~Some new sites give very nice bonuses and like I have mentioned earlier, giving them a trial is not a bad idea.
From my experience, you can win up to 0.01 BTC with 0.001 deposited on a new gambling site during a promotion. Only you shouldn't be too greedy thinking "What if I deposit 0.1? I can win 1 Bitcoin then!". Remember, dealing with newly appeared gambling sites is still very risky, and you might never see your deposited money again. And not because you can lose them to a game, but because you wouldn't be able to withdraw your balance from that site.
^ That was very risky because you do not know yet the new gambling either legit or what because they need first to prove their reputation first. Newly appeared or launched gambling site has expected that have a lot of promotion, faucet and other bonuses that make gamblers attract but it was so risky to deal with. Nevertheless, we should know the gambling site first before we make a decision to deposit our fund or you probably facing troubles in the future.
