I found that ViaBTC launched the cloud mining service again, and can purchase BTC & ETH contracts.
The prices seems reasonable and from their official press release, they said that there are referral rewards and discounts. Second market trading will also be supported later. Sounds good and may give it a try?
Cryptocurrency mining is a process used to create digital coins, like bitcoin. Computers are used to solve complex math problems to find coins that can be potentially worth a fortune. Many currencies require specialized, high powered machines that use large amounts of electricity, and create excess heat.
