Most cryptocurrencies are just a fallback for the actual financial system. It's basically electronic money for black markets. Evading government control is pretty much it's raison d'etre. The idea that you "invest" into this is only possible if you either keep recruiting members like a pyramid scheme or you bet on the collapse of the financial system.

These two positions aren't healthy. Even if the latter turns out to be true in the end, I would rather see a patch to the centralized financial system.
