Do you really believe this? Then why did Bitcoin and Ethereum lost their value? Did they become worse off? No, their technologies got better. Still, their price decreased a lot. It follows that markets do a poor job accessing an asset. Also, we saw many useless bitcoin forks that had huge gains. Again, that disprove the reasonability of your statement.
Markets often overvalue and undervalue.

But I believe that sooner or later markets will probably access an asset more or less reasonably. But looking at today values doesn't tell a thing about the real health of the project.
