4. Where are your mining farms?

Our farms are located in Inner Mongol, Sichuan, Sinkiang of China with the low electricity cost. We’d like to give site tours if you are interested.

5. Which pool are you using for cloud mining?

Our cloud mining contracts are mining in our own pool – pool.viabtc.com which adopts a PPS+ payout method. It allocates BOTH block reward and transaction fees (which now accounts for up to 10% of block reward) to offer much higher mining income.

6. Why don’t you mine yourself if cloud mining is profitable?

As it requires huge amount of investment for large-scale deployment of mining farms, we’d like to give away a part of our mining profits to users to dilute our risk as “not putting all eggs in one basket”. And also, we want “decentralization” in mining too so that global users will all have an easy chance to take part in mining.
