I see them as basically stocks. And no, it's not uncommon at all for anyone to promote something they have little understanding of. I didn't lose anything in thr crypto crash and still invest in it.
A Trilion? Only because they're worldwide and whale types were investing a lot. Some of them needed to be relieved of their money as far as the big ones. As far as the little ones, it's important to understand what you're investing in and the strengths and weaknesses. A friend explained to me the weaknesses on Luna nd Anchor protocol, so I held back on investing in it. I day trade and use USDT as my stable coin since it's the most stable of those types of coins. I was fine, just took a few days off.
