Why? Are you saying that countries should start adopting a crypto with a market cap of barely 1B$, that's been around for a less amount of time, that's significantly less battle tested and that never recovered to it's all time high value?

Do you think that the only thing that matters for crypto is speed and fees? You don't think trust/security/decentralization have any value?

Bitcoin chooses trust and security above everything else, as it should. Then you can have layers on top where you transact at the speed of network packets.
