It was officially put on hold from the end of 2019 as per the Github issue I linked to above, but that does not mean it is impossible or that no coins have been added since then. Exceptions have been made for notable coins - USDT, GRIN, and RSK are the ones which immediately spring to mind, but there have probably been others. The hold was essentially to stop any and every shitcoin applying to be listed just so they could use the fact they were listed as a marketing gimmick, all the while wasting Bisq developers' time and effort to support these coins/tokens which ended up with zero volume.

Although as we've just discussed in another thread, Robosats lets you use literally any payment method you like. Someone can always take their Bisq acquired bitcoin over there and list it for any shitcoin they desire. The combination of Bisq and Robosats is very attractive.
