What is the max supply of cru?

Can you please clarify what you mean by "cru" in the context of cryptocurrency and finance? Assuming you're referring to a specific cryptocurrency or asset, it's important to note that not all cryptocurrencies have a predetermined maximum supply. Some, like Bitcoin, have a hard cap on the total number of coins that can ever be mined, while others may have no such limit. If "cru" refers to a specific cryptocurrency with a maximum supply, I would recommend researching the project's whitepaper or official documentation to find the exact number. If you're unsure of the specific cryptocurrency being referenced, I suggest clarifying the term or providing more context to receive an accurate answer.
