Ouch, this brings back painful memories, I started mining at the start of 2017 but didn't have confidence that eth would last long term so I was selling my mined eth every month. I remember how each gtx1060 mined close to 7 eth over the whole year back then.

Really stupid of me to be selling monthly rather than saving all that eth. Took me a whole year before I finally stopped selling and started saving at the start of 2018. But by then each gtx1060 was only making something like 0.6 eth over the entire year.
