How to use Bitso?

Can you tell me more about how to use Bitso, the cryptocurrency exchange platform? I'm interested in learning the step-by-step process of signing up, verifying my account, and making my first trade. Are there any specific requirements I need to meet before I can start using Bitso? Additionally, I'm curious about the types of cryptocurrencies that are available for trading on the platform, as well as the fees associated with each transaction. Lastly, I'd like to know about the security measures in place to protect my funds and personal information. Can you provide a detailed explanation of how Bitso keeps its users safe?
