I'm relatively new to the world of cryptocurrency and I'm interested in utilizing Bittrex's P2P trading platform to make direct exchanges with other users. Can anyone provide me with some detailed information regarding the process of using this platform? Specifically, I'm interested in learning about the fees associated with the platform, any restrictions on the types of trades that can be made, and any helpful tips for using the platform. I'm also curious about how the platform ensures security for its users. Any advice or information would be greatly appreciated.
