When I first heard about Privacy coins like Zcash and Monero, I absolutely loved the idea. The benefits of a privacy blockchain potentially offer a lot of value.
However, I suspect soon many of these privacy won’t be around because of governments getting involved. Personally, I love BTC and don’t hold many privacy coins in my portfolio but with all the regulations coming, privacy coins may not be worth it.
The idea is still the same, people just don't care about privacy as much as they used to. Right now, all exchanges request KYC which means that your information is there somewhere in the world, and privacy is only left for people who would like to either hide themselves from the government for legal reasons or tax reasons and that’s it. Sure, there are some people who are fully legal and still use it but the numbers are very low.
So, you can see monero type of coins only on darknets when people are buying something. That’s why it’s quite important to not really focus on something that would matter, it's much better if you could focus on things that can make you money, instead of focusing on your privacy.
