Currency Review: Many years ago, I took a look through a telescope, and there are irreconcilable contradictions and conflicts of interest among more than 190 countries and regions in the world. The 'dog-eat-dog' situation will not stop, especially in the fields of trade, finance, and currency. They will always be distrustful of each other, and the noise is endless. Therefore, they will ultimately choose to play together with this decentralized trustless thing. Look, more and more people are playing, even Putin and Trump are playing.
