Do you have a source for that? If I'm not mistaken it was talked around here in the past about them taking the wallets and keys portion from cryptocurrencies.
If you read it I think its pretty clear that whatever they are talking about is totally unrelated to crypto.
But just thinking through it, the properties of crypto are the polar opposite of what a central bank wants out of the monetary system.
The last 80 years since Bretton woods has been the story of the US trying to centralize global markets around the dollar. The last thing they want is something that is either distributed or permissionless.
If you read the wiki for CBDCs it acknowledges this at the end after paying a bunch of lip service to how they were "inspired" by crypto.
> In contrast to cryptocurrencies, a central bank digital currency would be centrally controlled (even if it was on a distributed database), and so a blockchain or other distributed ledger would not be required or useful - even as they were the original inspiration for the concept.[24][25
That's the just of it. Many of these public ledgers, like Bitcoin, form a massive transaction graph. Blockchain analytics tools and companies de-anonymize nodes in these graphs by matching real-world transactions to blockchain transactions.
