"The 'Touch Grass' Allergen"

This is a physical condition resulting from an extreme crypto lifestyle. The person has pale skin due to lack of sunlight, dark circles under their eyes due to lack of sleep, and a hunched posture (Gamer Neck). They reject invitations to go outside ("Touch Grass") because they are afraid of missing market movements. For them, the real world has slow and boring graphics; their dopamine can only be triggered by green and red candles on a monitor screen.
