How much of a threat does cryptocurrency,especially Bitcoin, actually pose to the traditional financial system?

I’ve been trying to understand the potential economic impact of cryptocurrencies such as Bitcoin, particularly in relation to traditional banks, financial institutions, and government-issued currencies.

If cryptocurrency adoption continues to grow, could it eventually pose a serious threat to the traditional financial system? For example, could widespread use of Bitcoin reduce reliance on banks or weaken the role of official currencies? Or is Bitcoin still too volatile, limited in its practical use, and too small relative to the overall financial system to pose a genuine systemic threat?
