Finally, all businesses must return to their commercial essence. The essence of advertising is to sell traffic/endorsements, and the essence of blockchain does not generate value. The reason why BTC can maintain its upward trend is because the world needs something with a fixed total amount, and the halving mechanism ensures that the difficulty of subsequent mining increases. Therefore, BTC is a genius invention that attempts to use a written mechanism to ensure value, combined with VC's pursuit of high ROI and the US government's excessive issuance of currency, which has led to its current success. Any product can generate short-term hype, but if it goes against the essence of business, it will definitely not be able to cross the cycle.
