As a cryptocurrency enthusiast, I'm curious to know which wallets currently support ethpow, the proposed hard fork of Ethereum. Given the potential implications of this fork on the crypto ecosystem, it's important to stay updated on which wallets provide support for ethpow. With the diversity of wallets available, I'm interested in understanding which ones offer compatibility with this new chain, so that I can ensure my holdings are accessible and secure after the potential fork. Could you elaborate on the wallets that currently support ethpow, and if there are any specific considerations or steps I should take to prepare my digital assets?
