Except that's not clear at all.
It's currently less efficient than electronic bank ledgers by many orders of magnitude, in any way you measure -- energy consumption, cost, speed, etc.
And it's paradoxically less secure, as tons of successful hacks/thefts have proven. If my bank gets hacked, I'm still FDIC-insured. The courts will make me whole. Crypto is exactly the opposite.
And there is no indication any of this is changing. Crypto is inherently inefficient because of the need for proof, and for the average person it's far riskier so your money is far less secure in that sense -- and that's inherent too because illegal transactions like hacking and theft can't be undone, by design.
So the use cases of crypto are... not at all clear, except, really, for illegal transactions. Which is why the main real-world use cases, so far, have been... ransom payments, online recreational drug sales, and cross-border transactions. Not even remotely the "banks, financial instruments, and risk management" you're suggesting.
