Just remembered, a few days ago SEC Chairman Paul Atkins said: 'All U.S. markets will be on-chain within two years.' At least for the U.S., this is a very clear major trend. On-chain U.S. stock spot trading and on-chain U.S. stock futures trading platforms have already emerged, and more will continue to appear in the future. Will existing centralized platforms reform and dominate on-chain, or will emerging challengers successfully grab market share? How will related taxes be determined in the future?
