Mabsark wants you to buy this, because he is getting desperate about his Asicminer shares. But the offer is soo tempting that by his own words:


That said, I will agree that Amhash is far preferable over all the mining ponzi's like cloudmining.website, cloudminr.io, gaw, etc. Its arguably the least-worst cloud mining offer on the market. I still wouldnt chose it over coins in a cold wallet.
