Life After Merge

Once the merge is complete, ethereum will no longer be mineable.

This means that everyone mining ethereum will have to find other cryptocurrencies to direct their hash power to. There is a lot of money and equipment invested in Ethereum mining,

So there is no doubt that the miners large and small scale for other currencies will continue to pull out after the merge of Ethereum. considering that ETh is undermined with video cards etc. while BTC with asic with which mini only BTC, which are the most profitable and attractive POW coins? Will there be any volume explosion in the short but especially medium term (6 months) in any minor project? Kadena? ETC? Raven?
