Crypto wallets

Store your crypto always in a dedicated hardware wallet.

This is the safest way to store crypto.

But! Use this hardware wallet only to store your crypto.
Nowadays many hardware wallets have a lot of features like staking, games, Web 3 applications, financial contracts,....
Don't use those, before you know it you "sign" the wrong contract and all your crypto is gone from your wallet.
If you do want to use all those options, use a second hardware wallet for that.
Use one wallet just to store your crypto, the other wallet to experiment with all the possibilities wallets have to offer.
If something goes wrong, you only lose your funds that are on the experimental wallet.
Don't think it will never happen to you, even the most knowledgeable crypto investors get hacked by misusing their wallet.
