Unfortunately this is why I've given up on investing anything more in stocks or crypto. Everything I invested since before COVID is down.
My coinbase account currently has only 34% of the value I put into it 2 years ago, and I spread my investment over the top 5 hot currencies at that time (ethereum, cardano, algorand, sushi, bitcoin).
My stock investments are doing better at 65% of what I invested (tech, engineering, infra, pharma). Most are doing ok (down about 10%) but one in particular has absolutely tanked even though their pharma products are doing great and they've got two promising drugs in clinical trials. It's value has gone down 65% in the last year.
People will tell you to do you DD but the simple fact is, you can't. The market doesn't operate on any type of logic, a cat can do as well as a stock broker at picking stocks, and huge investment firms only win out in aggregate because they can (usually) absorb gigantic losses.
Right now I'm "bag holding" for the foreseeable. I consider these things "back pocket lottery tickets" that might one day give me a small win. But for the future I'm maxing out my pension and saving enough to buy a rental property, because one thing that has never dipped through boom and bust (at least where I live), is rent.
Edit: I lie, part of my TC is stock, so wherever I work, I am "investing in them" too
