There are a few classic typo memes in the crypto community that have now become cultural symbols.

The earliest, HODL, originated on a Bitcoin forum when someone got drunk and typed "hodl" instead of "hold." The whole community started using it to mean "hold and never sell."

Later, the tech crowd in Ethereum came up with a variation—Buidl, intentionally misspelling "build" to imply "less talk, more action; focus on building."

Then there’s the Safu meme, which comes from CZ’s catchy phrase "Funds are safu." "Safe" was typed as "safu," and it turned out to be even more memorable. Now whenever people talk about fund security, they love using this word.

Recently, another one called DOYR has popped up, reportedly from a leading female figure in the space. In this community, typo culture is no longer just about typing errors—it’s more like a secret code for identity.
