Well, yes and no.  They took away 5 yr contracts in August.  Last week they took away 24 hr contracts, too.  So if you are a new user from the USA, there is no way to actually purchase any Gh/s at all.  You can mine for it using hardware miners or rentals from outside the site, or you can claim from the faucet.  But that's it.

They have posted nothing about it on their site, they are still allowing new US users to sign up, deposit, etc. But no mention of the fact that one thing you really cannot do at this cloud mining site if you are from the US is actual cloud mining.
