What is cot business?

Could you please clarify what exactly you mean by "cot business"? I'm not immediately familiar with this specific term in the cryptocurrency or finance context. Is it a reference to a particular type of trading or investment strategy? Or perhaps it's a slang term used in a specific community or industry? Without more context, it's difficult for me to provide an accurate description. However, I'm happy to help explore the possibilities and see if we can find a relevant explanation. Could you provide any additional information or clarify your question?
