If you look at the concurrent user numbers on Steam, it seems like there's overwhelming engagement in the gaming space right now. I thought the same as you until I looked into it a bit more.
(Also, bitcoin is mined on ASICs nowadays, but I get what you mean.)
I've never heard of other crypto currencies referred to as Bitcoin by anyone other than noobs. It's like calling the Mexican Peso a Dollar. The semantics are important - i.e. for doing something like currency conversions.
Are we noobs here or is this a tech forum where people might reasonably be expected to know the difference between Bitcoin and Ethereum? I'd argue it's the latter.
You can't say that Bitcoin is responsible in a discussion about GPU shortages. It's flat-out wrong and obfuscates the actual problem. It's Ethereum that's mostly responsible for said shortage, and seeing as how Ethereum is moving to proof of stake soon that problem might be alleviated. Bitcoin uses all custom hardware for mining and is not affecting the GPU shortage. The problem with Bitcoin mining is power consumption, not chip contention.
That will be actually fun. Make a company invest in some random crypto coins, presents movements. Just call all of them bitcoin... Argue that at this point it is generic name... Skim your fees from top.
