Trading BTC for XMR, XMR for BTC, back and forth. It still hides your footprints and can't be prevented from a government.
Sure, but XMR isn't being used a currency - it is being used a surrogate mixer effectively. BTC is the currency in this scenario.
Do you still think that having Bitcoin globally adopted instead of a CBDC is a possibility? I highly doubt it.
I'm sure governments will push for their CBDCs relentlessly, but I'm also sure that bitcoin will continue to become more popular over time.
Besides, if it's possible to retain privacy, what makes you think the world won't start educating each other?
We already do, and yet Windows is the most popular OS despite being spyware, Chrome is the most popular browser despite being spyware, and Facebook is the most popular social media site despite being spyware. What makes you think the masses will suddenly become interested in privacy when they start using bitcoin?
