What is GG slang for?

Excuse me, could you please clarify what the slang term "GG" stands for in the context of cryptocurrency or finance? I've come across it a few times but haven't been able to pin down a definitive meaning. Is it an acronym for a specific term or phrase related to the industry? Or perhaps it's a shorthand for a common sentiment or expression among traders and investors? I'd appreciate any insight you could provide.
