China's rare earth strategy is very similar to Ethereum's de facto anti ASIC strategy back then. First, we told the United States that we would export (we will soon switch to PoS), but the overseas rare earth supply chain and production capacity cannot start because no one dares to invest (mining machine manufacturers dare not develop because they will always switch to PoS quickly). Finally, Ethereum took 7 years to complete the PoS conversion, far exceeding the originally planned 2-3 years.
