concrete hands

A term used to describe a person's situation when they have invested in a cryptocurrency and hold a token for extended periods of time, through ups and downs, not because of conviction, hope or mental fortitude (as in the case of diamond hands), but rather, because they have lost their private keys and have no choice but to hold forever without ever being able to realise the gains.

Diamond hands is about holding a cryptocurrency even when it capitulates on the conviction or hope that it will some day rise again. With diamond hands, the investor has the optionality to sell some time in the future.

By contrast, with concrete hands, you're stuck, forced to ride market cycles and deal with the psychological torture of never being able to cash out your investment if it turns out well, all because you lost your private keys.

Bertie: Poor JT, the guy bought 100 BTC in 2013 but lost his keys and can't access them.

Benny: Ah, that's terrible, that's the worst case of concrete hands I've come across.
