There are many kooky economic experiments in crypto right now that are not only 1) Not failing miserably, but 2) Are growing steadily. Decentralized financial products like MakerDAO and Compound Finance are very interesting. Augur is a prediction marketplace that was pilloried for having some 30 users per day when it launched, but now has around $2 million in open interest.

It is very early days, and it is quite complicated to build new products and businesses given that the tooling is poor, the crypto networks are slow, and many mainstream technologists take endless pleasure in shitting on crypto and cheering when prices fall, but progress continues.

I think cryptocurrencies and smart contracts have earned a seat at the table for disruptive technologies of the 21st century, along with cloud computing, AI / ML / big data, and smart phones.
