How much is one GG?

Excuse me, I'm curious about something. I've been hearing people mention this term "GG" in the cryptocurrency circles, and I'm not quite sure what it stands for or how much it's worth. Could you perhaps clarify for me? I understand that the value of cryptocurrencies can be quite volatile, but is there a general idea of how much one GG is worth at the moment? Any insight you could provide would be greatly appreciated.
