Could you please elaborate on the process of selling cryptocurrencies on Quidax? What steps do I need to follow to initiate a sell order? Do I need to have a verified account, and if so, what kind of verifications are required? Also, what are the fees associated with selling on Quidax, and how are they calculated? Is there a minimum or maximum amount I can sell at a time? Lastly, what happens after I confirm my sell order? Do I receive the proceeds directly in my bank account or is there a holding period?
