In September 2022, Ethereum is scheduled to start ETH 2.0's Merge upgrade. Some exchanges will support its potential hard fork. If successful, the Merge could create two parallel blockchains after the upgrade.
EthereumPoW (ETHW) is a PoW-based token created from the hard fork of Ethereum. Tradable on several exchanges, users can claim ETHW using their Metamask wallet on the ETHPoW network. ETHW has a different inflation rate than Ethereum on PoS due to its PoW consensus.
