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?
So, you are talking about faucet gambling site, I don't think it is really effective to the level where it may help you make a living with such site. In fact, faucet sites are big waste of time. I suggest you should try to rank-up your account here on this community by posting positive comments and join the signature campaign that would be better.
