#BTCvsETH highlights the debate between Bitcoin and Ethereum as leaders of the crypto market. $BTC is seen as a store of value ('digital gold'), with a limited supply and robust security via Proof of Work, but criticized for its lack of flexibility and high energy consumption. On the other hand, $ETH is praised for its utility in smart contracts, DeFi, and NFTs, as well as the migration to Proof of Stake which reduced carbon emissions. Critics, however, question the centralization of the Ethereum network after the Merge and the complexity of its ecosystem. Both attract different profiles: long-term investors prefer BTC, while developers and users of crypto applications tend to favor ETH. The balance between security, scalability, and utility fuels the debate.
