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?
My 2 cents for you my friend is to always double check the links and these sites you are referring to. When you feel its too good to be true the try to get away from it as much as possible. Why would people try to give free btc if most of it are willing to pay for it at a high price. Im not saying that all of them are scams but this would be a good thought process.
