some cloud mining allowed about it and i use it with my cgminer 
I disagree they have a lot of hidden fees ! go see https://www.nimbusmining.com i have been using them since April i can chose my pool and they have no HIDDEN FEES.
No one mentioned how overpriced their GHS is, it's waste of money to deal with any of those companies. BTW you can use nicehash, you will get ghs lot cheaper and you can point it wherever you want
