We already know that FreeBitco.in is a legit faucet, but the basic amount, which is also the most frequent, is really low.
Fortunetly, the faucet has a HI-LO game where you can multiply your earnings. While people are talking about luck, I'm talking about strategy.
I'll take it as simple as possible. The idea is to start with a basic bet amount. After every lose, you are going to double your bet amount. In doing so, after n rolls, you are still going to make a little profit. After every win, you are going back to the basic bet amount.
