Tsinghua University has started to popularize virtual currency. What does this indicate?

Today, while browsing Douyin, I came across a course on virtual currency by Tsinghua University, focusing on BTC and ETH. I thought I was mistaken. Can mainland official media and top academic institutions openly promote this now? Is the mainland about to open up? Wasn't it said to be a Ponzi scheme? #下一个换谁涨？ $BTC $ETH $XRP
