How do you reconcile the fact that most of Web3 is built on Ethereum which only works because miners ("soon to be" stakers) are rewarded for running the blockchain?
According to what? According to the global charts on Coinmarketcap, Ethereum is still around 20% of the total marketcap of cryptocurrencies (BTC being at ~40%) today, coming from growth since January 2020 (where Ethereum started at ~7.5%). By that metric, Ethereum seems to be growing, but you might have a better source/metric to share?
