They are based in US and I assuming that everyone would expect this to happen after all the fuss about the US government considers these privacy coins as a problem.
I wonder what's gonna happen to all the exchanges outside the US but I think in the future all the US citizens will be forbidden from using such privacy coins by the US based exchange. Gonna be a tough time for these privacy coins I guess.
All exchanges outside the US I don't think will bother with privacy coins, for example Binance is not concerned with privacy coins and Binance is not delisting privacy coins,
If I look at it, it's time for privacy coins to upgrade the network, like XCASH coin,
XCASH network offers both privacy and public so it is more flexible when compared to other privacy coins.
As does Dash, remember Dash is a fork from Bitcoin so it too has a public viewable blockchain and provide optional privacy on its transactions if users choose for that.
With Bitcoin that optional privacy happens through Bitcoin Privacy wallets, that connect to Tor and create CoinJoin transactions on the Bitcoin network
With Dash that optional privacy happens inside the Dash Core wallet, that create CoinJoin transactions on the Dash network (Dash just calls those PrivateSend transactions)
With Dash those CoinJoin / PrivateSend transactions are currently between 1-3 % of all transactions (there rest are all public transactions, fully tracable)

has grown since 2019, which is not unreasonable to think with the popularity of Bitcoin's Privacy wallets, like the Wasabi privacy wallet).
Bitcoin CoinJoin transactions will likely grow even more, when scaling solutions like these get implemented :
