September 13th, Alex Blania, CEO of Worldcoin, spoke at the Token2049 roundtable conference in Singapore, stating that although there are no exact numbers, a simplified model for universal basic income (UBI) is to assume a 5% annual economic output growth rate and continuous increase through some linear function. In the next 10 to 20 years, it is possible that certain groups will actually receive basic income security payments through cryptocurrency, which is exciting. In addition to basic income security, cryptocurrency can help us build social tools to adapt to the development of new technologies. This is of great significance for the future development of cryptocurrency.
