Most sites are legit alright, in terms of the money they pay out. The problem is that faucets are simply not worth your time. The activities you are required to do and the ads you have to watch take so much of your time and the btc they give you is so small that you are better off doing something else. Don't waste your time on faucets.
I came across this site where people can roll the dice, earn free bitcoins and also multiply them. How legit are these sites and how to use them effectively?
He/she is right. Most faucets are paying but it's not worth it to do. I knew it because I'd already do wasted my time in that faucet claiming to make only 1 cent in a day. Why do that when you can do more than that.
