How does CoinMetro work?

Excuse me, could you please explain in more detail how CoinMetro operates? I'm curious about the platform's functionality and how it facilitates cryptocurrency trading. Specifically, how do users access the platform, what types of assets can be traded, and what security measures are in place to protect users' funds and personal information? Additionally, are there any unique features that set CoinMetro apart from other cryptocurrency exchanges? Thank you for your time.
