noun | kuh·stuh·dee
Custody is like being grounded by your parents, except instead of not being able to go to the mall, you can't access your own fucking money. It's when you give up control of your crypto to some third party (like an exchange or a wallet provider) and just hope they don't pull a Mt. Gox and yeet all your funds into the shadow realm.
Example
"Not your keys, not your crypto' is the GOAT of custody advice. If you don't hold your own private keys, you're basically just letting someone else raw dog your funds."
"I learned the hard way that leaving your crypto in the custody of an exchange is like leaving your weed with the cops - you're probably never gonna see that shit again, and if you do, it might be all stomped on and sprinkled with Oregano."
"Imagine letting a boomer bank have custody of your Bitcoin. That's like letting your grandma hold onto your Juul - she's probably just gonna throw it away and tell you that 'smoking is bad for you, sweaty.' Smh."
