According to the No. 1 financial institute, Zheng Lei, chief economist of Baoxin Financial, said in an interview that the characteristics of blockchain technology have given the blockchain token economy no bad currency to drive out good coins. The truthful records and information sharing of the blockchain will make counterfeiters or perpetrators lose more than they pay. Because once found, the main body of this kind of behavior will be disqualified from continuing to participate in economic activities. This loss has a sufficient deterrent force, making all participants dare not do bad things, cannot do bad things, and do not want to do bad things. The formation of a pattern of good coins expelling bad coins is beneficial to everyone.
