Good thing Bitcoin mining hasn’t been done with GPUs in several years. You can blame cryptocurrency mining for the high GPU prices but not Bitcoin mining.
Speak for yourself. I'm currently earning $13-15 a day by mining with my RTX 3090.
The RTX 3090 FE costs around $1500 after tax, but I bought it off craigslist for $2000 (after fruitlessly waiting for months for the stock to become available). I should have just bought it back off craigslist back in September or October. If I had paid the scalper prices and just started mining with it back then, it would have already almost paid for itself by now.
Yeah, I thought that people mine Ethereum with GPUs, which is somehow related to BTC in terms of price (I have no idea how tho, I guess people trade ETH for BTC and vice versa)
As I understand the cryptocurrency markets, they basically all move in tandem with Bitcoin. So if Bitcoin's price goes up, so do all other cryptocurrencies.
Also instructive to see prices of altcoins in terms of BTC. Barely anything moves up. There are very temporary spikes, but mostly it's all one giant opportunity cost compared to just holding BTC.
