I am still searching for a decentralized solution to use once and for all. However after reviewing more than 10 different solutions I have not found a working one. I will keep looking and may put up a bounty for someone to make it. Until then you can use the site: https://www.changenow.io Normally this exchange is unlimited and requires no registration. However be warned that they may freeze exchanges if their KYC system kicks in. I have had only good experiences with them so far and have not experienced a freeze, but you should still do trades in segments so losing a trade won't fuck you over completely. It says on their site that redeeming a frozen exchange will require ID so yeah, not ideal. Obviously you should use the site with the TOR browser if you want to remain anonymous.
