this place used to be a bit more "hey get your first free satoshis entering the crypto world" where newbies who had absolutely no crypto at all had an entry point here.
Nowadays it's a giant, it's probably either the biggest crypto related website ever, or at least high at the top of the rankings and having some cpu mining situation wouldn't really be profitable at all, people are wagering 100+ btc daily here now, and that shows you how big it got.
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

There is no question that FreeBitco.in is still the king and the world's largest and most popular Bitcoin faucet. It has over 60 million visitors monthly (according to similarweb.com) and almost 50 million registered users, which is far more than its competition. However, I think that FreeBitco.in is not only a good faucet, but also a great place for new Bitcoin users to learn more about Bitcoin. I believe the purpose of the faucet goes beyond generating revenue; it also serves to educate people about digital currencies, to showcase Bitcoin's usefulness, and to encourage adoption.
