well, it is a bit of contradition if crypto needs banks to change the world...
In the end I see two paths, or the banks, as we know them, die and crypto allows a bank-free society, which will be difficult because although parasites, the banks accumulate some degree of power in our society and will not go down easily.
Or the banks adapt, the same people stay in control and the system and money just changes to crypto instead of printed paper.
