Here's yet another nail in the coffin for us GPU Ethereum miners, another Ethash ASIC miner on the horizon...sometime soon.

"Dubbed Project Lavasnow, Linzhi's new ethereum miner claims to use 1/8th the amount of electricity as Bitmain's ethash miners,
according to a presentation Chen developed for the Ethereum Classic Summit held this week. It also expects to run 1,400 million
hashes per second, compared to 190 from one of Bitmain's AntMiners."
