noun | kohld wah·lit
A device that stores your crypto offline, usually in the form of a USB stick or a hardware wallet that looks like a Tamagotchi from the year 2045.
Example
"I lost my cold wallet in a tragic boating accident. And by 'boating accident,' I mean I got high and microwaved it because I thought it was a Hot Pocket."
"Using a cold wallet is like wearing a chastity belt for your crypto - sure, it keeps your coins safe from hackers and thieves, but it also means you can't access them without a lot of awkward fumbling and cursing."
