I have a very important question:

The U.S. protects itself from China, and rightly so, blocking any communication channels or apps that pose a threat, especially if they were developed in China.  

But what about a currency developed in China? Who knows who is behind it, and maybe it's a Chinese AI spying on the whole world?  

How is it possible that they developed it to be so slow and so expensive? 
After all, the Chinese are known for developing things quickly and cheaply.  
Have you ever thought about this?
