Firstly, don't waste your time on surfing faucets for earning very small amount of bitcoins because it doesn't worth the time, you won't earn a reasonable amount even if you spend all day on it.
And secondly, invest your money in gambling or HYIPs only if you don't love your money, because they are really no way of earning bitcoins, they will just cause you loss in any sort of way, better to put your money in trading and earn some profit after learning how to trade.
