i read an articel at bitcoin.com about a new miner from Pangolin and the miner is called Whatsminer M10. i dont know if the group has already spoken about this machine but i just wanted to let this little information here. maybe its interesting for future investments. if it is allowed i would share the link.
Whatsminer M10 actually looks like quite a decent miner, the only more efficient BTC miners out there are the ASICminer 8 Nano Pro/Compact (which is horribly overpriced). Still waiting to see what the Antminer S11 specs will be though.
Bitmain Antminer S9j = 0.0107 Th/s per Watt
Pangolin Whatsminer M10 = 0.0154 Th/s per Watt
ASICminer 8 Nano Pro = 0.0190 Th/s per Watt
