According to ChainCatcher, Justin Sun tweeted that he was happy to have a conversation with Mr. Song Hongbing about the future of currency. We both believe that the right to issue currency and the right to keep accounts are essential to a healthy and complete financial ecosystem. Decentralizing the maintenance of these two rights is the most fair and optimal choice for all mankind. The design model of blockchain is the answer to the future of human finance. Finance should be a right that everyone enjoys, just like freedom of speech and freedom of belief.
