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.
Not a big minner and I thought that it's impossible to do that nowadays. But it works and it gains the rewards. I'm glad.
Unfortunately, it's stopped working, no responds and request, nothing at all
