Hopium is a portmanteau of the words 'hope' and 'opium,' used to describe a state of irrational or delusional optimism, often in the face of overwhelming evidence to the contrary. While its roots can be traced back to early 2000s political discourse, the term exploded in popularity within the cryptocurrency and stock trading communities on platforms like 4chan and Reddit. The visual representation typically features Pepe the Frog or a Wojak character wearing a gas mask or inhaling deeply from a tank labeled 'Hopium.' It serves as a satirical commentary on 'true believers' who refuse to give up on a failing investment or a lost cause, often paired with its counterpart 'Copium.' Today, it is a staple of internet culture used to mock anyone relying on blind faith rather than reality.
