Almost all countries around the world have money laundering as one of their problems, and even though the government of each country has a solution, exploitative people also have an alternative way to their illegal activities in reality.
So I think that money laundering will never disappear because even though cryptocurrency was created in our era, there are only two types of people, it is the good or the bad, which means that cryptocurrency can be used for good or bad, depending on the intention of the person who wants to enter this industry. Whether you are a government official of a country or not.
