From the AMHash website:
Higher ROI
AMHash has a low cost on both initial price and maintenance fee.The maintenance is only $1.633 per day per TH,which equals to $0.07/kwh.
The fee has been lowered to $1.551/DAY/TH now though.
So that means that the higher maintenance fee was also bringing undisclosed profit for AMHash. Nice.
Since AM has the most efficient chip on the market (please correct me if I'm wrong), AM may be able to use the strong bear market as an advantage to regain a larger portion of network hashrate.
I think you mean
sample chips.
