Could you please elaborate on whether Coinbase, a leading cryptocurrency exchange platform, currently supports Ethereum's Proof of Work (ETH PoW) consensus mechanism? With the recent transition of Ethereum to Proof of Stake (ETH PoS), there has been a lot of discussion around the future of mining and the role of PoW. Given Coinbase's prominence in the crypto space, it's crucial to understand if they continue to support ETH PoW tokens or if they have shifted their focus solely to ETH PoS. Clarifying this information would provide valuable insight to crypto investors and miners alike.
