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.
Yeah that's correct, you need to make a deposit, wager or buy tickets to get to 4 sats/roll. The think I like about freebitco.in is that always find a way to give even more to the users: a couple of years ago they started giving out a 4.08% interest on your saving and then recently they gave us the WOF spins.
