Beginning with the fact that cryptocurrency was originally built in some sort as a mean to avoid banks and the bureacracy related to those kind of thing, is there any use for bank to launch their crypto, why would people who are searching for a non-centralized way to manage their asset to join centralization expert like JPM or other
There will be more advantages than possible disadvantages in my opinion. The real use case is more important than judging the centralized or decentralized ecosystem. Not every bank will create its own personal cryptocurrency but they will try to implement new features with this system.
