What is ref currency?
Excuse me, could you please clarify what you mean by "ref currency"? Is it a specific term related to cryptocurrency or finance that I'm not familiar with? If it stands for a reference currency, I can explain that it's typically used as a benchmark for measuring the value of other currencies or assets. It's a common practice in finance, especially in the context of foreign exchange markets, where one currency is used as a basis for comparison to evaluate the value of another currency. Could you tell me more about the context in which you've come across the term "ref currency" to help me provide a more accurate explanation?
