Crypto is hardly a "sector of the economy". It's main utility right now is lining the pockets of a few speculators.

Traditional centralized ledgering systems do everything crypto does better and with a fraction of the energy use. It also gives governments tools to combat inflation/deflation and manage counterparty risks within the system.

Crypto is a neat idea, but in the end it doesn't really solve anything, and instead only introduces a lot of unnecessary problems.
