Are Privacy Coins Good Investments? 

Every volatile cryptocurrencies assets with use cases are good investments. Privacy coins would have been the perfect cryptocurrency asset because of their private nature. The fact that transaction details are only visible to the sender and receiver makes them ideal for those who want to enjoy privacy.

With the current crackdown on major public blockchains like Solana, Cardano, Matic, etc, you will agree with me that privacy coins won't even stand a chance against regulators. Some privacy coins have been banned in some countries. The only reason why regulators have not come for them is the fact that their dealings are not that popular to attract regulators.
Regulators may allow public blockchains to continue their operation after identifying with them because they ( regulators) can track transactions unlike in privacy coins where it is almost impossible to do so. Privacy coins were built to protect whales and individuals from the public eye, and this nature of privacy coins may be a problem for them in the future.

Now to the question, are privacy coins a good investment?

The trading volume of these privacy coins is quite high. As of the time of this writing, Monero, the leading privacy coin by market capitalization ( 2.74B) has a 24-hour trading volume of $75M. Other privacy coins have trading volume in the figures of $20M, to $50M. This shows that lots of trading are going on in these coins despite not being hyped. For one who is looking at leveraging volatility to make profits, investing in short-term trading is a good one. You can trade them for the time being pending when regulators will remember them.

But do we need privacy coins?

It is quite true that one can scan wallet addresses on Explorers and be able to see the assets therein, but it doesn't give the person access to the wallet.
Again, outside those using domain names, wallet addresses are not easily traceable to owners. The only time you can identify a wallet address is when you receive tokens from someone you know.

So, privacy coins are not a necessity in the crypto world.
