Selecting a Mining Pool
ViaBTC is a mining pool that also offers cloud mining contracts. You can even contract out your antminer.
Mine Bitcoin on ViaBTC and participate in “Mine and Share 100 Million CET”
ViaBTC also has an exchange called Coinex with its own token CET. They frequently run promotions involving the token and also dividend share with CET holders.
Last time I checked S9 Contracts are available
