What would happen if cryptocurrencies take over?

Imagine a scenario where cryptocurrencies were to dominate the global financial landscape. Would traditional banking institutions still hold their ground, or would they be forced to adapt and adopt these digital currencies? Would governments retain their monopoly on monetary policy, or would the decentralized nature of cryptocurrencies render them powerless? How would international trade be affected, given the borderless and frictionless nature of crypto transactions? And perhaps most importantly, would the average consumer benefit from this transition, experiencing lower fees, faster transactions, and greater financial inclusion? Or would the volatility and complexity of the crypto market be too much for most to handle? These are just some of the questions that arise when considering the potential implications of a cryptocurrency takeover.
