What is the minimum send amount on Coinbase?

Could you please clarify for me the minimum send amount required on Coinbase? I've been considering using their platform for some cryptocurrency transactions, but I'm not quite sure about the specific details. Is there a set minimum amount that I need to send in order to use their services, or does it vary depending on the type of cryptocurrency or other factors? It would be greatly appreciated if you could provide some insight into this matter. Thank you for your time and assistance.
