How to sell astr?

Could you elaborate on the process for selling ASTR tokens? I'm particularly interested in understanding the steps involved and any potential pitfalls I should be aware of. What are the best platforms to use for selling ASTR? Are there any fees associated with the transaction? Additionally, how do I ensure that I receive the correct amount of fiat currency or cryptocurrency in exchange for my ASTR tokens? Is there a minimum or maximum amount of ASTR I can sell at a time? Any advice or insights you could provide would be greatly appreciated.
