I agree with the closing paragraph and for me that is true. US isn't taking of the advantage that they have been open to this technology and instead of helping and cultivating this kind of innovation, they are stopping it. And this how China sees the big opportunity that they can take since US is ignoring this. It's now starting, China is starting to lead and I don't know how they can be taken over by US again in terms of technology but in this era, it's important matter to know that data is the new kind of treasure chest like gold and that can be stored on a blockchain.
The US didn't public doesn't mean that they ignore it. Who know? Maybe US have been researching and developing about Blockchain technology, testing national cryptocurrency secretly. Chinese government is acting like they are positive to cryptocurrency. It's not mean they are the leading.
