BTCHeat is a scam. They are using your processor power to mine for themselves and giving you in return worthless free spins to their site. Once you reach the withdraw, they will not let you withdraw and raise the withdrawal limit. This is a new kind of scam which is making a lot of victims from newbies who are not well informed about such scams.
DEFINITIVE SCAM.
I also think that this site is a scam, there is no chance to get to 35 mBTC, after few days I saw that and no matter how free spins you get and try, you will need months to get to that amount. Time is not so big problem, what I believe is that they will not pay that amount in the end when someone is finally get to that, they look like a scam site, we will see will anyone take some bitcoin from them.
Coinpot is also a good faucet portal.
And I can add that this is one of the easiest faucets, you just open it and that is all you need to do. I still didn't make any withdraws, but I'm close to that, we will see what will happen with that.
