According to the Digital Legal Coin Research Agency, Lu Lei, Vice President of the People's Bank of China, said in the preface of Money Theory that if the central bank can have no bottom line and unlimited currency issuance, then the currency is likely to be replaced by other general equivalents - such as digital assets and stable currencies, whose market value fluctuates upward. Is it really going to be like this? As someone who has been engaged in research work in central banks for a long time, my intuitive idea is that the urgent problem facing major developed economies is to 'rescue central banks from the hands of central bankers'.  @rduray7
