According to CoinMeta, Vitalik Buterin indicates that Bitcoin users deserve a great deal of praise for pioneering many concepts (such as utreexo). He pointed out that the currently proposed Ethereum expansion strategies are being implemented, and he hopes that Ethereum will be able to combine UTXO style states, dynamic states, and everything in between, allowing most Ethereum activities to achieve scalability without sacrificing decentralization, node operational convenience, and resistance to censorship.
