Im not feeling good with privacy coin right now consider people are starting to abandon it but it looks like some people might still use privacy coin like monero. i think that privacy coin will not be the global trend. The government was doing various things to get the date from the exchange site. Here's the main concern when people are actively using centralized exchange site and privacy coin means nothing as the data will be collected by exchange site but the privacy will be useful only for peer to peer transaction that will not involve the 3rd party like centralized exchange site.
