In the specific context of Bitcoin it may be true that the preference is for ASIC, but (1) some Bitcoin is still mined using GPU's and (2) there are several thousand active digital currencies, many of them favoring GPU's.

Grandparent's wider assertion is absolutely true, the GPU market is skewed by miners. Purchasing a 3000 series GPU is not easy right now.

Do you have a source for (1)?

I'm pretty sure GPU mining btc is inefficient even with free electricity (depreciation of the PC/GPU will outweigh benefits)

edit: was curious so checked the math

Using a 3060TI GPU (one of the most cost-efficient for performance gpu's available) would generate about $0.0002/day, or take ~5000 years to pay itself off even with free electricity

Doesn't bitcoin compute time go up with computational advances also? If so, any answer greater than a few years can be transposed to infinite time to cover costs.
