How do I start trading cryptocurrencies on Bigone?

Could you elaborate on the process of initiating cryptocurrency trading on Bigone? As a newcomer to the platform, I'm interested in understanding the key steps required to get started. What sort of verification process should I expect? Do I need to fund my account in advance, or can I start trading directly with digital currencies? What types of cryptocurrencies are supported, and are there any specific limitations I should be aware of? Lastly, how do I navigate the platform to execute trades efficiently? I'd appreciate a detailed walkthrough to ensure a smooth trading experience.
