To date, the political situation in the world is very tense, especially since there are a lot of military conflicts, while various kinds of terrorist organizations and crime only exacerbate the situation. Each government fights against these phenomena, as well as against illegal money laundering, as well as corruption within their countries. Based on this, it must be borne in mind that no one can hope for one hundred percent anonymity using cryptocurrency for its intended purpose. Of course, for the time being, traders and investors can exchange and trade cryptocurrency on decentralized platforms, but it seems to me that in this situation, when the government is interested in specific means, wallet addresses or an exchange platform, law enforcement agencies will immediately receive all the information that interests them, Perhaps even personal user data.
