Diamond hands is crypto and stock market slang referring to investors or traders who hold onto their positions through extreme volatility and price declines, refusing to sell regardless of losses. The term became popular during the 2021 GameStop short squeeze and in cryptocurrency communities, where it is contrasted with 'paper hands' — those who sell at the first sign of a downturn.
Example
“Despite Bitcoin dropping 50% from its all-time high, the diamond-hands holder refused to sell, confident the price would eventually recover.”
