I think that the argument of growth being too high is a fairly flawed argument and you've pretty much just proved why. These are only some of the most well known stocks as well, there would be some very obscure stocks which have probably enjoyed even greater returns.

The main difference comes back to the 'intrinsic' value argument. It's clear to see what these stocks are supported by because it's a company and their revenue and then the dividend that they'll pay out.

With bitcoin that is missing and that's why I think people make such an argument (I don't want to get in to the intrinsic value argument but I'll just quickly say that I don't believe in it because all values are intrinsic so it's not anything new to bitcoin).
