Cloud mining has never been viable since each gh/s of mining power you buy has the cost of electricity plus other fees attached to it. Just normal mining is difficult, therefore, cloud mining is a waste of time, especially if you invest in that little hashrate. Be careful of which cloud mining sites you use if you decide to go into cloud mining, 9/10 of them are ponzi schemes that call themselves cloud mining sites. If you want to get into mining, then buy the equipment on your own and run your mining operation from somewhere where you wont have to pay for electricity (like work).
