How do I Sell cryptocurrencies on advcash?

Could you please elaborate on the process of selling cryptocurrencies on ADVcash? I'm specifically interested in understanding the steps involved and any key considerations I should be aware of. Is there a minimum or maximum amount I can sell? What are the associated fees? How long does the transaction typically take? And are there any security measures I should implement to ensure a smooth and secure transaction? Your insight would be greatly appreciated.
