How do I sell crypto tokens?

Hello, I'm new to the world of cryptocurrency and I'm wondering how I can sell my crypto tokens. Could you guide me through the process? I've heard about various platforms and exchanges, but I'm not sure which one to choose. I'd like to understand the steps involved, such as choosing a secure exchange, creating an account, verifying my identity, depositing my tokens, placing a sell order, and withdrawing the proceeds. Additionally, I'm concerned about taxes and any legal requirements I need to be aware of. Could you provide some insights on these aspects as well? Thank you for your help in navigating this process.
