I sold off my entire farm last year except for 1 rig and I'm mining UBIQ.
It's true 1060s can scrape a little money off ETH even at 10 cents but you have to consider that 1060 3gb cards are being sold on eBay for $70 when they were going for $150-$200 last year at this time. I took the proceeds from liquidating my rigs and bought ETH at $7x during the dip.
So I faired a lot better by getting out and if I want to get back in I can liquidate the ETH and buy 2060s to mine with but they seem meh at this point.
The 1060 3GB tanked the most out of all the second hand GPU market because around the time that the Crypto markets were crashing and profitability was going down, they could no longer mine ETH due to the DAG being too large to fit in the 3GB of GDDR.
Also how did you buy ETH at the $70's range when the lowest price it ever hit on most exchanges was around $80.50 or so. Last time it was $70 was actually exactly 2 years ago in May 2017.
