Banks have massive power, not only economic power but also political power, as their top executives have contacts with most Governments and political parties of the world

Being realistic I don't think crypto will destroy the banking system in its current form BUT if we start gaining momentum with mass adoption and people start saving with Crypto instead of a banking account, we can start to take away the unlimited power banks hold right now.

We need to mature as a market and a space to get more people to save in crypto and really start creating a more decentralized economy and society.
