I think decentralized versions of everything will replace the existing structures because they ensure true democracy and trustworthiness.
Decentralized social media platforms, marketplaces, news websites, fintech services. We're at the beginning of a massive overhaul!
of course the first to feel it is a bank, because in addition to the blockchain system there is a cryptocurrency, both of which are interrelated. therefore bank must adjust the situation to remain in existence
Banks will certainly deal with this "problem". They will adopt blockchain to their own needs using the existing cryptocurrency experiences. After all, bankers observe what is happening in the world of finance and technologies used there and react to emerging threats or opportunities that they may use for their own purposes.
