partners lists may not be updated periodically; I have referred to them and that list has not been updated for some time.
I believe they might take some time before they add new partners to the list but we all can see that they're very active on this forum and on this announcement thread that's what matters more than anything else.
I've used CCE.CASH at least two times and I never faced any issue with it, and that's why I believe it's one of the best platforms for no KYC traders because it offers lowest trading fees and that also means a lot for many traders.
And, when it comes to unstoppable then I don't think that it's an official partner of CCE.CASH. It might use API integration instead to bring CCE.CASH on the bot.
And I think the PARTNERS list is more of a “places we are listed” or “companies that use us or are used in any way by us”
When a swap has an API they will be connected to make aggregators, wallets and websites.
All we can know is that CCE.cash has very good rates and can be trusted, so they will only grow more from here
