Where can I sell Propy?

Could you please provide me with some insight on where I could potentially sell my holdings in Propy? I've been following the market for a while now and am considering liquidating some of my assets. I've heard of various exchanges and platforms but am unsure which ones offer the most secure and efficient way to sell Propy. Could you recommend a few trusted options, perhaps highlighting their features, security measures, and user experience? It would be greatly appreciated as I want to ensure I make the right decision for my financial portfolio.
