"Nobody" is an exaggeration. There is a big community of enthusiasts who enjoy cryptocurrencies for what they are and enable, not for their USD value in the markets.
Is what they enable worth $40.000 to the enthusiasts?
I won't make the case for cryptocurrencies here, have a look at ethereum.org for instance.

I'm not denying that the current price hike and media attention has little to do with any other aspect than "decentralized ponzi"/dollar escape. Was just correcting a false statement.
