A lot of my crypto students have been questioning about the best wallet to store their crypto assets. some of them thought that a crypto exchanger is suitable.

Well, i educated them that the best wallet they could ever use is a cold wallet but if they don't have money yet for a cold wallet, they should go for non-custodial wallet rather than a custodial wallet.

A custodial wallet denies you the ability to own the keys to your wallet, so when the wallet crashes, your coins are gone but a non-custodial wallet permits you to own the keys to your wallet and prevent loss of coins in the event of the wallet crashing.
