It's bitter to see this happening in the crypto space, crypto users are gradually being deprived of their right to select privacy coins hence the market is being compromised by things in the traditional systems of the world. Privacy coins should for no reason be delisted, I don't see anything wrong with it. The crypto space should not allow what is obtainable in the conventional world oppress our will for variety.
One of the reasons they do it is that the high-privacy cryptocurrencies are used by the criminal world more often than Bitcoin. Monero is the most popular crypto among those, who have evel intentions. Zcash is also used. However, delisting from the list of exchanges and lower prices do not slow down the development of privacy technologies in cryptocurrencies. Zcash Electric Coin released Halo, a technology that will further enhance the privacy of this crypto.
