I think it has a cut-and-dry explanation - they got wealthy with the exact opposite method - credit, debt, and fiat products. These guys aren't dumb, they understand the whole financial system would change if we moved to hard money like Bitcoin.

What I don't get is they won't be around for it, so why be resistant against the winds of change when you won't even live through it?

Because it erodes their privilege. The "great investors" aren't any smarter, they just have institutional access to investment vehicles that the rest of the world is "classed out" of either by minimum investment requirements in the millions, by private access outside the public market, or by "risk assessments" that make it a requirement to be a certified "expert" to take part. This is how they make their money, not by being smart, but by being on top of the pyramid. Bitcoin is something everyone can access. Dirty prole investment. Bah.

Because they dont understand it. They also didnt get in at the right time and are now too stubborn to change their opinion.
