After ETFs and strategic reserves, whether Bitcoin can open a second growth curve in mainstream countries around the world depends entirely on the International Monetary Fund's attitude. A country like South Korea, which has such a high acceptance of virtual currencies, announced today that its central bank is not considering establishing Bitcoin reserves for now, considering reasons that contradict the guidelines of the International Monetary Fund. In early March, the International Monetary Fund also directly pressured Savart to no longer use Bitcoin as a currency and to stop mining, buying Bitcoin, and other activities, otherwise it would extend the $1.4 billion financing provided. Therefore, the International Monetary Fund can be said to be very "hostile" to Bitcoin, after all, they hold trillions of dollars in fund scheduling capabilities and also have the power to directly rate all countries in the world. Therefore, mainstream countries can only succumb to the tyranny of the International Monetary Fund, which is also the main reason for the slow or even stagnant promotion of strategic reserves in many countries. Therefore, if the International Monetary Fund ever loosens its grip on Bitcoin, its legitimacy will skyrocket from being limited to individual countries like the United States to global legitimacy. This positive news will be nuclear grade for Bitcoin, and we can closely monitor the direction of the International Monetary Fund in the future.
