Directly? Not a lot.
Indirectly, it kickstarted global CBDCs research, blockchain-integration research across major financial institutions, tokenisation efforts, etc.
Would all these things have happened anyway? Yeah, maybe. I don’t know if blockchains in the form we got them were necessary, but they surely are this possible world’s ignition.
Will this all be beneficial in the long run? TBD. But, the story isn’t over yet.
Crypto was possibly a net fuck up though
