This type of investing isn't about day trading following the latest hype. It's about putting some surplus money to better use for when you need it in 10-20 years.
If everyone is passively investing, that no longer works. Then it's not even a market. We don't even know, for sure, if that works.
If you use big index funds, you're the primary people contributing to Nvidia, Tesla, and openAI. You didn't start it, no, but you certainly propelled that ball forward like a bullet.
And, well, that's fine, because we cant expect anyone really to actively invest. The problem is we don't know if this works. This definitely has the potential to blow up. You have to realize that what we're doing here is undermining the stock market at a conceptual level.
