Mining since Feb. 2014, total fiat outlay back then was $10k. Now up to 330THs, all upgrades and expansion paid for from BTC earned. I have double-digits of BTC in reserve. Left BM long ago and getting Avalons through Canaan's US distributor Blokforge so no import/duty charges.
Please, tell me exactly how I am not getting ROI?
That fiat of $10K USD would have given you around 16-17 bitcoins if purchased directly without mining. Do you have more than 16-17 BTC now, and if so, is it significantly more?
