Um, after reading that, I change my mind.
Cloud mining is not good investment. The logical is, if a cloud mining service have a ton of hashrate, why they don't use that to generate coin to their self? That's is risky. Buy a miner hardware is better than make a contract with cloud mining service

If I lost my 70GH/s because BCS became a scam, I'll still in zero lost, because the money that I used for contract is come from a giveaway
