Perhaps the disappearance of the banks would have been possible if the development of the bitcoin had happened as it was originally planned, where bitcoin users would base their economic exchanges on mutual trust, but at present big capital seems to have taken control of the market and they seem to have the power to move the bitcoin according to their interests, therefore sooner or later there will be a greater integration between the current banking system and the cryptocurrencies, as in fact it seems to be happening nowadays.
