I think it's also good to get rid of the worries of people who have been stolen, who think that transactions recorded on the blockchain are one of the causes but not 100%. that means it doesn't always all start from the walle address of each person whose transaction is recorded on the blockchain. precisely if the government gives the legalization of bitcoin, it can be important to detect the transaction. if the transaction is in large quantities, the government can track it whether it is a money laundering, or some kind of illegal transaction to buy drugs.
