Alien Cloud presents a cloud mining platform, a mining pool, a cryptocurrency exchange, and a wallet. There's not much info about the company. It is believed that the company is located in Russia although there are no accurate data to dispute or prove it.
Speaking of cloud mining, we should say that on Alien Cloud users can be "lifetime" contracts. There are many currencies to choose from (including Bitcoin, Bitcoin Cash, NEO, Litecoin, Monero, etc). The prices are quite low.
Unfortunately, it's stopped working, no responds and request, nothing at all
