Back last November I bought a AMD Sapphire Radeon RX480 Nitro+ OC 8GB GPU for £225 ($290).
Today, 8 months later I have just sold it for £310 ($400) due to the hype around Ethereum Mining (the newer form of Bit Mining). In fact, Nvidia 1070 cards are now nearly as much as 1080Ti cards! Just crazy!
OK, so I had some spare cash to buy a 1080Ti, but that has just been offset by £310 ($400)!
If you have an AMD card, then I would seriously consider selling it!
