OP, where do you have the Shiba stored, to start with? I believe it shouldn't be an exchange since you abhor them now after your supposedly bad experiences. Where, exactly? I'm not sure if Shiba has a private wallet at the moment (I couldn't find any on playstore, though). Nonetheless, if you're looking for a P2P kind of arrangement for the sale of your Shiba; I suggest you use an escrow. An escrow service will keep both the buyer and seller save from scam. The user above @GbitG has already provided you a link on getting escrow.
