I don't invest in diamonds (I had to buy a few, but that was an investment of different kind), and I don't really invest in the stockmarket either for the reasons you mentioned.
I can make enough money to live comfortably through work, admitedly I would be a lot safer if I had more, I prefer investing in realestate that I can potentially monetise by renting and I can leave to my children. It's probably not the most efficient but I don't want to spend time and effort on investing in to stockmarket, crypto or w/e - I chose SW development because I like to build things that solve problems and be creative - at this point crypto/stocks feel like the exact opposite (initially I gave it the benefit of a doubt but at this point I'm almost certain it's a bubble built on spreading bullshit)
