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
Its not useful but people don't understand the benefits of decentralization, and the risks of centralization. But everyone is giving a try at their own crypto, Governments as well. Not that i would recommend them... In the past it used to be fashionable for companies to issue their own credit cards, so i expect them to start issuing their own cryptos as well, just because they can.
But in the end most altcoins won't survive.
