Bitcoin is more and more regulated by the authorities, and few people will like it. Therefore, it is absolutely natural that many will think about using privacy coins.
On what basis do you say this?
Do you have more evidence for that now ? Because I see there are already more people who like Bitcoin (including some state parties). So what you say in my opinion is very wrong, because Bitcoin is the first well-known asset and is also worth more than just a privacy coin. And it looks like you need to read more news on some well-known sites so you can compare the number of Bitcoin enthusiasts to the current number of privacy coin enthusiasts.
I only say this based on the news I read. Everyone chooses which coins are better to use. You can use any coins you want, now there are a huge number of alternatives and I decided to choose privacy.
