Is Curve like PayPal?

Could you please elaborate on how Curve compares to PayPal? While both seem to facilitate transactions and payments, I'm curious about the key differences in their functionality, target audiences, and the cryptocurrencies they support. Does Curve offer the same level of convenience and security as PayPal, or are there specific advantages that make it unique in the world of digital finance? Additionally, what are the fees associated with using Curve, and how do they differ from PayPal's fee structure? I'm interested in hearing your perspective on these points.
