Freebitco.in when I first registered in 2014 it was just a faucet but at that time their idea of faucet was the best of all to roll the dice once every hour and they made it so that you could even win big if you hit the lucky number.Back at that time the idea was great and as a result a lot of people joined,with the passing of time Freebitco.in team kept introducing new feature for the better and for all the users,if you read for example financial books you can apply those rules here,like trading with the token they have,getting daily interest and so on,it is like a game in which you can build something and here you can build money if you have enough time,intelligence and of course referrals.I personally like it a lot as to what it has become since 2014.
