I bought some sha256 and scrypt contracts from hashflare last year. I was really happy to have done so at the right time just before the boom of btc.
Then guess what happened? Hasflare unilaterally reduced the term of my contracts to 1 year and doubled the maintenance fees based on a clause (which would normally not meant to become effective without any material adverse change). However out of greed, they decided to grasp the upside of their customers by changing the terms of their initial promise without any valid reason but greed and greed only.
I could have easily get those contracts from genesis mining or somewhere else. What they did is shameless.
I will never buy again from these crooks. I hope some guys can sue them and they will face huge penalties. Customer protection laws would normally not allow such stupid clauses to overrule the law and always protect the customers.
Even if things go super good in crypto world, they will not let the customers benefit from that anyways so i dont recommend you to buy from hashflare either
