Basically I had my RX 470 4GB since 2016. In 2018 I started to sell them and honestly nobody was buying them. Gamers basically only wanted an idea. I would make an ad on Craigslist and It would take maybe a month or two to sell for $75. Most of the time I got nothing but messages like “I know you mined with this GPU I will give you $25 cash , today”.
Now with the last of my RX 470 they all sold for like $150 or so. And not only that but they sold in like a day or two and there were no low ballers.
So just realize this that once the dust settles and you want to sell your RX 470 it will be worth maybe $50 and will take forever to sell. So maybe right now is the time to liquidate them.
