In 2021, I invested part of my USDC into pooltogether through the imtoken wallet operation and received the corresponding pcusdc credentials. At present, imtoken is no longer open to users and cannot be connected to the pooltogether platform. Currently only PCUSDC is in the wallet. How do I get my assets? Can I send PCUSDC to another wallet and retrieve assets through that wallet to the pooltogether platform? What wallet can operate?
