i'm aware of splash.tf, but the thing is... i mainly use LTC and USDT to pay for stuff/withdraw from sites, which i then swap to bitcoin to add to my stash as needed.
but sadly they don't support either. they do offer DAI as a pair, but not many of the sites i use support it for payments.
i had it soo good with eXch

If you think better, splash.tf is defined based on the advantages and disadvantages of eXch.
For example, USDT has always been questionable on truly no-KYC services, due to its centralization and the risk of locking the token at any time. Also, they are not aligned with the MiCA regulation, which will eventually distance USDT from the countries that adhere to it (EU).
eXch has always hinted at a possible transition to DAI (when it comes to stablecoins)
Doesn't look bad, considering that they are still quite new. Have you tried the, an if yes whats your feedback?
Tried several times. Only a positive experience, plus the exchange rate is quite competitive. One of the best when compared to other instant exchanges. I once had a problem with the RBF function, but their support solved it in a very short time, and soon after they fixed the "bug".
Lack of USDt wouldn't be such a big problem for me as it is for Zwei as I don't mind DAI, but their reserves are quite low, and so is the volume. Hopefully that changes in the future. Anyway, I'll definitely keep an eye of them.
They were aware of the problem of small reserves and announced an increase. As far as I can see, these days they have added more DAI coins to the reserves, so it can be said that they are monitoring the situation.
Obviously, only at the beginning, but I see them as the most serious for the potential successors of eXch.
