Privacy coins are not worth it at all. It just brings down extra scrutiny and regulation. Look at what Binance and Kraken did to Monero. They caved into regulatory pressure and de-listed it. The price of Monero hasn't moved in years.
The price of Monero has not moved in years due to its faulty tokenomics. That said it is a coin that protects its users from
the governments - and due to this phenomenon its price has become relatively stable. Delistings are not a problem as long as due to privacy features and low fees the currency such as Monero remains transactional.
