I think this can happen. In the future, the blockchain may replace banking operations and become the main system for the circulation of all financial assets. But this is still a very long way. But he in my opinion has already begun and will be undisputed.
Many, many years into the future,,, if at all. The problem today is 99% of new blockchain projects that get the attention of people including bounty hunters are all corporate projects. Worse, all linked to banks. And now banks and MNCs are all patenting blockchain tech.
What started as a challenge to banks now the banks are fighting to privatize and monopilize.
