You cannot compare crypto and stocks. In stocks you have the ownership of capital. And you can live off of capital. In crypto all you have is ownership of a number. And off of number you cannot live.
Maybe not, but that's the closest thing we have since there's never been anything like it before. By the same measure, we can't compare it to numbers in an excel spreadsheet either, right? Because, obviously, it has some value (at least for now) whereas the numbers in excel are pretty much worthless.
I would rather have the guarantee that in 10 years I will have 90 percent of the equivalence of my house back, than faith in anonymous people. For me, 10 percent inflation in the years is not a problem. Although I never keep my money for so long.
Yes, but that's poor people thinking. Each investment comes with certain risks; the question is how much risk you are willing to take. In the case of cryptocurrencies, history has shown that the risk has certainly paid off, but it is definitely not for the fainthearted.

Btw, what do you mean, "I never keep my money for so long"? What do you do with it, if it's not a secret?
How do you know that in 10 years people will give you even 1 percent the value of your house that you traded for bitcoin today?
The truth is, we can't. No one can. That's the fun part.
