^ You did not understand yet what is BTC.
BTC transactions can be made directly between individuals without the need for intermediaries like banks or credit card companies, this decentralized and transparent nature of BTC has the potential to disrupt traditional financial systems in several ways, but I don't like the word disrupt here, it could be an alternative to fiat.
Several ways as I mentioned could be because of lower transaction costs, faster transactions in online payment, and last global accessibility which can be across any borders. So for me, probably there is a small chance that has the potential to disrupt our financial landscape by providing a decentralized and transparent alternative to traditional financial systems.
