Hi All,

Newbie here. I would like to ask how can I mine bitcoin using my rpi3 using a 5v 2.1amp usb port to power my rpi and usb minerBTC. Is this possible?
Also If I use usb hub, is it enough to use 5v usb port to power my hub?

Another question is where can I buy usb miners / block erupters? Is gekkoscience the ideal usb miners this days?

Note: I am fully aware that it will cost me more than what I gain. I just want to make one.

Thanks in advance.

Regards
