What does the CR symbol mean?

Excuse me, I'm quite fascinated by the world of finance and cryptocurrencies, but there's one symbol that's been puzzling me for a while. Could you possibly clarify for me what the CR symbol stands for? I've seen it in various financial contexts, but I'm not quite sure what its specific meaning is. Is it related to a particular type of currency, a trading platform, or perhaps a regulatory body? I'd appreciate any insight you could provide.
