I totally agree. Maybe traditional banks will disappear but the new and improved ones will remain, even if crypto takes over the world, the banks will also start using cryptos or create their own ones. A financial institution like a bank will exist as long as we use money and work for money, no matter what their money is. Why should they close the banks when they can still make a lot of money. And if you look at it, most of the money the back uses is electronic anyway, from there to crypto is just a small step.
