Cloud mining schemes are rarely profitable. They will force you to agree to terms that will state they can terminate your contract at any point in time if THEY feel that it is no longer profitable to continue with the hash rate that you bought. Many have lost bitcoins on cloud mining with Genesis. You only need to google "is cloud mining profitable" to see that many people will agree with me.
Stay away from cloud mining and invest in something else.
This. Hashflare recently changed their unlimited btc contracts to one year lifetime. Impossible to ROI if something like that happens.
