Maybe it's just me and my age and how long I've been here but for me this is still the "hey get free satoshi for nothing" deal. Sure, it's only 4 sats per roll now but there's always the chance at $200, there's always the free lotto, and the daily free WoF spin all for nothing.
Roll 5 times and you get 1 cent worth of bitcoin. It's still a load more than PTC sites. Payout is still pretty decently low.
Of course the site's moved on now to bigger and better things but I still feel the basis of free bitcoin is true

If I'm not mistaken, a minimum prize for new users is only 1 sat per roll. So users should wager enough or buy lottery tickets to be able to get 4 sats or more per roll. Anyway, I think free rolls every hour are already secondary on freebitcoin because this website has long become more than just a faucet.
