What is the best multi coin wallet that supports self custody and I can use to hold memecoins as well as btc and ethereum?
Trust wallet is a okay wallet that support variety of cryptocurrencies I but suggest you use a non custodial wallet that is open source like Unstoppable. Metamask is also another good option.
How bothered should I be about privacy too? I hear it’s a top consideration in the crypto space
Privacy is very important. You will want to keep your seed phrase private, and be careful when sharing your personal information on websites. I’d advice you use a non-custodial wallet to store your coins so you have full ownership of your coins and use decentralized exchanges.
