scroll down and look at the pricing history of the rx 470: https://www.videocardbenchmark.net/gpu.php?gpu=Radeon+RX+470 and the 480: https://www.videocardbenchmark.net/gpu.php?gpu=Radeon+RX+480

Notice what happened during the alt-coin bubble?

Now go look at nvidia's stock price around that time. Everything went bonkers in May.

So I understand what you are saying, but there is clear historical evidence for my claims. When it comes to market manias the safest place to make money from it is adjacent to it in a way that supplies the maniacs.

The cyptocurrencies that can be mined with video cards are different from bitcoin. Ethereum is probably what you are thinking of being mined by GPUs.

obviously it's for the less valuable coins with lower difficulties.

It's not obvious if you call them bitcoin when that isn't their name. That's like calling 7-UP a coke.

ok, but 7-up adjacent companies are coke adjacent companies; canning, sugar, labeling ...

I don't know what you are saying. You can't mine bitcoin with a GPU. You can mine ethereum and probably other cryptocurrencies with GPUs. Bitcoin is a specific cryptocurrency. Nothing you are going to say is going to change that reality.
