Since 2016, over $2 billion has been lost because people have their private key compromised. Not your key not your coins, but be smart or it will be your key but not your coins.

Since 2016 the majority of capital that is being lost in defi is through private key being compromised. Many crypto companies with multisigs have also been compromised, an example can be the whole pepe situation that is going on right now.

A common phrase we all hear is not your keys not your coins, which is very true but also remember that if you have your own keys you should know what you are doing or learn to keep it safe. If you don't keep it safe it will be your key but not your coins.

The biggest mistake people do with their seed phrases is storing it online. Do not do that. That's the fastest way to get your assets stolen.
