There are many people globally without access to traditional banking infrastructure. In more financially "developed" countries this is not an issue, however around 1 billion people don't have access to this infrastructure. These people can access crypto without needing to sign up and custody their assets with an institution. As for China's dominance in mining, it doesn't mean they can control or overturn any Bitcoin transactions. The open source transparent code that Bitcoin and most cryptos have allow for someone to use financial infrastructure on blockchain without trusting a third party. Xi Jinping was referring to the digital Yuan which, when implemented, will allow for complete surveillance on the Chinese people. This will be a centralized fiat crypto which is not what I'm referencing to as trustless access to financial services. DeFi and the savings mechanism that Bitcoin allows one to do almost anything they could do with traditional finance without trusting a third party. When you own and control your own money via crypto, you have independent monetary control which was what I was referencing.
