smart to sell in september, i feel for the poor bastards that bought your paperweights, they cost $900 or so with shipping im sure you didn’t get over $200 for them still a nice investment but i still would rather hold crpto than buy gear atm. To make it worse with yeild farming the profitablity from just holding and farming tokens crushes mining even more.
I probably still can sell them now

Looks like ppl still want to buy those E3's , there is a ebay search result from today , 12/15/2020 11.20PM EST

Bid prices still going up close to 800$
