Someone please guess what the cheapest gh/$ will be and what the most cheapest and expensive units they could make. I need info, so I can prepare to get a loan. I want the most expensive products they have, please.

Because usa 20 amp households are limited to about 1920 watts continuous power. I don't think they could practically sell a unit more than 1.9 th/s based on the 1 watt per gigahash.

So, how much would a 1.5 TH/s unit cost? bitfury 400 gh/s units go for .05 gigahash per usa dollar while kncminer 400 gh/s unit goes for about .056 per usa dollar.

lets say that cointerra units sell for .15 gigahash per usa dollar. that would be 10k usa dollars. 

thats too expensive for me
