With Ethereum rising 6%, today I saw an analysis from an E-guard: he believes that in the future, Bitcoin is likely to merge into the Ethereum (ETH) network and become a special token in Ethereum, relying on Ethereum's Proof of Stake (POS) to ensure security. In the Bitcoin economic model, as the halving process progresses, block rewards continue to decrease, and the income structure of miners does indeed change. Issues such as an increased risk of 51% attacks objectively exist.
