But a graphics card can't be worth $0 like a cryptocurrency. Even the RX 580 8 GB graphics card can play many modern games and its price will not fall below $100 if it is in good condition. Even if it is cheaper, then what price will the RX 550 2GB have? RX 560 4gb? RX 570 4gb?
I agree with your general idea of GPUs having gaming value, but I don't think we are anywhere near the price floor for current-gen video cards. RTX 3060's are selling for $330 used today, but let's say they end up at $200 in 3 months if today's coin prices stay steady. That is a capital loss of $130 / 90 days = $1.44/day.
You will get $0.60/day of profit mining CFX at free power. That won't compensate for the $1.44 in capital loss. So the most profitable decision would be to sell that RTX 3060 today rather than take the -$0.84/day = $75 of loss over the next 3 months.
After I did the math, I came to the conclusion to sell *now* instead of riding the market down.
Coin farm ventures when do you think it's the best time to start buying GPU? With the way you sound it seems like you knew when the bottom will be, what's your target for BTC and ETH on the long run through this bear market? ETH is under 1000$ right now, maybe we are heading for 700$ per ETH?
