In my view, this site is strong evidence for the thesis that demand for GPUs will plummet, here's why:
1) If we tweak your link to sort by Market Cap, we can see the next biggest coin to mine after ETH is has only 1% of ETH's market cap https://shorturl.at/lxLS5
2) These smaller coins do not have the capability to automatically or naturally grow bigger market caps, trading volumes, and buy-side demand just because ETH switches to PoS. Mining profitability ultimately comes from a coin's buy-side demand, which is proportional to many things-- fame, developer activity, etc.-- and none of the PoW chains in that list are anywhere remotely close to "breaking out" and growing proportionally with Ethereum, or, say, Solana. How do I know this? Well, I'm an insider that focuses all of his time on ethereum and web3, you'll have to take my word for it :)
As someone rather naive in regards to cryptocurrency, I don't understand what you're basing this on:
> These smaller coins do not have the capability to automatically or naturally grow bigger market caps, trading volumes, and buy-side demand just because ETH switches to PoS.
What would they need to cross that barrier? For example, don't all coins have the ability to manipulate trade volume by sending money between owned wallets?
Sending money between two wallets you own creates transaction volume not trade volume. The latter comes from orders matching against each other on an exchange and requires paying the exchange fees so it is not as easy to fake (you need the exchange itself to be in on it, or they take all your money in fees).
Can you translate for people (like me) who don't know what all those numbers are supposed to represent? I can't make sense of it or relate any of them to GPU demand.
I don't understand much of the site either, but at a high level, my guess is that it's sorting crypto coins by computation required vs $$$. Right now ETH is at the top, aka for every flop you put it, you get the most return, but there are many others not far behind. So even if you were to eliminate Etherium entirely, there would still be plenty other that are profitable to mine.
Why sell a GPU for a fraction of the price, when you can just switch over to another coin and make 50-90% of the money you were making still.
If you have a GPU you could use it to "mine" various coins. That site calculates which of them is currently the most profitable and how much profit you're likely to make with a given hardware configuration
