Is Bitcoin really a good business? It's a tough question to answer definitively.

The cryptocurrency market in the first half of this year was quite exhilarating—Bitcoin once surged above $60,000, then dropped below $30,000. During this period, some people made huge profits, others suffered heavy losses, some cursed at the moment of liquidation, and some reflected on whether they had been too greedy.

Economist Wang Yongli's view is quite straightforward: don’t see Bitcoin as a guaranteed money-making scheme, and dreaming of it to overthrow national currencies is wishful thinking. In China, there has never been much interest in Bitcoin, while the US treats it as a serious business. This difference in attitude actually reflects the varying perceptions of this asset in different markets.

Interestingly, this phenomenon has historical precedents. Over 2,000 years ago, Guan Zhong engaged in an arbitrage trick called "Qí Wán Lǔ Gǎo"—exchanging cheap goods for the other party’s scarce commodities, ultimately earning a fortune. The story of Bitcoin seems to have some similarities, only the stage has shifted to the global financial market, with participants changing from ancient merchants to modern investors.
