Cryptocurrency and Bitcoin has bloomed since 2009, and still going upward.
Some commercial banks, including some investment banks, introduce their own cryptocurrencies for the purposes of settlements and transactions with certain financial institutions and corporations.
What commercial bank that has successfully launched their own native token and becomes usable in their business and operation? If there are, they're not popular at all and with those CBDCs, they're still in the phase of adoption and distribution. But most people that are in the location of those CBDCs that are about to be launched, I don't find news about interests about it.
At the moment, central banking is not interested in cryptocurrencies, but this may change in the future.
And it will definitely do.
We'll never know how interested they are. Some may just turn by surprise and announce that they've been a bitcoin investor. Bitcoin as an asset is what they're looking at and not as a currency.
