I must say I only use freebitco a few times a week when I remember it, betting on something where there is a 50% chance will not lead to anything, you most likely end up losing your moeny or wasting your time to win back a few satoshis.
What I like with freebitco are that you can bet on events, I use all the faucet satoshi on event betting.
You should try to claim the faucet every hour.
Besides the free satoshi you will get lottery ticket.
Lottery ticket is a big thing on that site. If you'll gonna keep checking the lottery winner history most of the time there are winners who only have few lottery ticket. Like less than 2k lottery ticket and they are winning .1 Bitcoin plus. Never had the chance to win yet but trying to earn more ticket give me chance to win on the future.
