Can you make a daughterboard for the A1 chip or one like the A1 hashrate?
With one bitfury you never come to ROI.
I realize 1 or even a few bitfury chips will probably never ROI. but this is not a serious investment vehicle.
This is a serious lesson in pcb design concepts for me designing it , but taken as a whole is a fun learning xperience.
As for the A1. That may come later down my hobbyist road in DIY home brew electronics
