Not all investors will value the term privacy when dealing with crypto as the purpose of creating monero is to promote anonymity, investors still go for coins with higher profit and zero privacy as seen in most cases, Monero is also preferable by most people who value their privacy. I think the choice depends on every investor and this is not just a forceful opinion to hold Monero but rather it has to do choice, I still think the reason why most people don't value Monero is due to the private nature.
Of course. Investors wouldn't want to buy something that isn't regulatory-compliant. They want something that's seen with good eyes by the government to ensure their investment lasts a long time. I'd say governments have successfully destroyed privacy coins' reputation by labeling them as tools used for criminal activities (money laundering, tax evasion, terrorist financing). The public is now skeptical of getting into something that's used by wrongdoers. We all know that's not really the case, especially when Fiat is still the #1 tool for criminals (due to its ease of use and greater accessibility). But the harm is already done, with Monero and similar coins losing popularity each day.
It's likely all CEXs will cease trading of privacy coins (XMR included) in the future. Fortunately, people can use alternative methods to continue buying/selling privacy coins. You can thank their decentralized and censorship-resistant design for that. Considering that Monero is the biggest and most successful privacy coin in the world, I'm certain it will survive for generations. No matter the price of XMR, we should be thankful for having a means to achieve privacy and financial freedom. Who needs "Wall Street", anyways?
