"Do you have a sufficient understanding of stock markets?"
For most people that's a "yes". They know what stocks are, what they represent, who the big players are to buy stocks on your behalf, and can be assured that the money is going to get to the right place.
This is just not the case for crypto (yet), not remotely. Tons of tech people hardly know how these things work.
I'm responding to the way the op phrased their initial statements. They implied that just because they did not have a deep understanding of something, it must be bad.
Crypto is something for them that they don't understand, just like the stock market is something that many people also don't understand.
