Many new privacy coins are crap, they offer new features that the teams aren't ready to back up, that veil coin promised a stealth function, sending coin from a stealth address to another but that feature doesn't work till date and team aren't saying anything about it, another one is mask coin, failed in the end
This is why some exchanges are delisting those privacy coins since they arent the types that centralized market will love to. In exxeption with the monero which is the most sophisticated and I believe the good one amongst the rest. Its up to you to interpret how this projects will roll. But I dont have much hate with them as their object is pretty simple and nurturing the true decentralized.
In this case the problem is anonymous coin will never be free from the regulation. The problem is to get the users and this anonymous coin will always need the help from centralized exchange site. The majority of centralized exchange site that comply with the regulation will always give responsibility to the users to complete the verification. Anonymous feature can be used only for people to people transaction only.
