A cryptocurrency wallet is a digital bank account for your crypto. It’s where you store, send, and receive your digital assets. A self-custodial wallet is a type of cryptocurrency wallet where you have complete control over your private keys, which are like a password to your crypto. You can store your crypto directly on your own device, like a phone or computer, without relying on a third party, like an exchange. Setting up a self-custodial wallet is easy with apps like MyEtherWallet or Metamask. Having control over your own private keys is important for ensuring the security of your crypto, especially in today’s world with increasing cyber attacks. affiliate products, sponsors and social.
