For ego maybe but its not cost effective:
It cost maunfacturers $500-600 per TH now and thats only 1.5w/gh performance, KNC cant even buy at price because they dont manufacture the chips themselves. Prob cost them $1000 TH to build their machines.
Samsonn25, no bitcoin ASIC miner company manufactures their own chips. They all have similar design and foundry costs.
