China's state controlled television explaining the basics of "first ever
blockchain technology" #bitcoin $btc, and how a distributed ledger works
Imagine 1.3 billion people got to know bitcoin because state made an effort to explain how it works.
You're reading way too much into it.
Whenever you will talk about the inception of blockchain, like it or not, Bitcoin gonna come in discussion. Xi Zinping clearly talked about embracing blockchain technology which could be disruptive tech in many sectors. He didn't talk about lifting any kind of ban that Chinese government has imposed on cryto.
Moreover, don't just assume that the whole population of 1.3 Billion gonna watch it. State controlled channels' reach isn't that high.
