How do I sell on Bifrost?

Could you please explain the process of selling cryptocurrencies on Bifrost in a step-by-step manner? As a new user, I'm curious about the necessary steps and considerations before initiating a sale. For instance, do I need to have a verified account? What are the transaction fees? And how long does the selling process typically take? Additionally, are there any security measures I should be aware of to protect my funds while conducting the transaction? I'd appreciate a detailed overview of the selling process on Bifrost.
