Ok, here is a wierd thought: It is arguable how good is cryptocurrency versus widely adopted fiat and all of already existing banking infrastructure.

But there is a niche where blockchain outshines existing technologies by orders of magnitude. And this is stock markets.

I mean modern stocks are still papers with fancy stamps, that are regulated by legislation and enforcement. And also there is a very complex financial and legal infrastructure to keep those stocks of different companies tradeable across the globe. And smart contract blockchain reduces this infrastructure and legislation enforcement bureaucracy  to distributed network of computers.

World combined market cap of all paper assets is near $300trln.

All we need to move it to all-around better blockchain infrastructure is just legislation about smart contracts. A crypto stock should be legal equivalent of an ordinary stock if its coded to work the same way a stock would work.
