Spacemining is a cloud mining service that gives 100 GH of bitcoin mining power just for signing up. It’s been open to the public for 14 days. I got in on the second day of business and have already had my ROI. These contracts are lifetime contracts or life of the profitability to mine. The prices are reasonable as well. I added a photo to prove my payouts. As you can see I’ve already withdrawn my initial investment of 106 dollars. I will leave my link if you are interested. Thank you.
