I disagree with all the others re: cloud mining.
I've invested in open-ended BTC mining and 2yr Ether mining with Genesis Mining and both have ROI'ed already and is now earning income.
But with regards to Hashflare. I'm currently researching on them because all contracts in Genesis have ran out and I'm considering them an option. But like what I said in this thread: https://bitcointalk.org/index.php?topic=1152278, I have some reservations.
1. How in the world can they keep up and not run out of hash power? Even if they are backed by Hashcoin, how can they keep up with Hashflare's auto-reinvest feature and with all the demand for cloud mining. All the other reputable competitors have ran out.
2. Where's the farm? I know they have some pictures in Instagram. But I don't see a farm there. I can set-up something like those in a any small room.
With these 2 things in mind and with the current issues they are having with withdrawals, I'm really apprehensive about buying anything from them.
