Diamond Hands

Diamond hands means refusing to sell through drawdowns — the 2021-era badge of conviction holding, usually rendered as 💎🙌. In 2026 the term is mostly used ironically: unironically diamond-handing a memecoin to zero is indistinguishable from copium. Its opposite is paper hands, the jeet’s natural state.

The phrase peaked with the 2021 GameStop and dog-coin cycles and now reads as vintage slang — deployed for comic effect rather than as sincere advice. The durable insight underneath it: an exit plan chosen in advance beats a slogan chosen mid-drawdown. COPEAI grades vocabulary, not trades; this one is filed under "historical copium."
