Professor Lang Xianping is once again live streaming in an authoritative manner, banging the table and gesticulating while discussing economics and finance. There were only about a thousand people online, and I exited the live stream in three seconds. Could you talk about the phenomenon of Bitcoin, which is currently priced at $93,000 each, with no real economy and without endorsement from the state, government, or central bank? He doesn't understand that public sentiment is the greatest politics and the most pervasive finance. The global and indiscriminate public sentiment serves as the greatest financial endorsement and also the largest real economy. He just doesn't get this, and he talks all day about currency, land, and state endorsements.
