I recently found out about this site Microhash. I heard they offered some free hashpower so why not check it out.
CHECK IT OUT ----> Microhash
FREE HASHPOWER WITH THIS LINK^^^^^^^
They promise really high returns, so i wouldn't recommend investing anything your worried about losing. If you sign up earlier enough you can definitely get a payout. INVEST AT YOUR OWN RISK. I am going to try putting in a few dollars and see how it works out.
