Does lowest up-front cost and no maintenance fees sound to good to be true?
Does the cloud mining service try to hide their maintenance and trade fees until you've already bought a contract?
Does it refuse to provide proof that they even have any miners?
Are you concerned that the cloud mining service is actually a ponzi?
Well, now you can get cloud mining direct from ASICMiner, one of the earliest manufacturers of Bitcoin ASICs. There's no question about these guys actually having miners and they provide all the information you need to make an informed decision.
Cost: 1.2 mBTC per Gh/s
Maintenance fees: $0.00163 per Gh/s per day
