One of the requirements from the state is the identification of individuals participating in financial transactions and the sources of their funds. KYC (Know Your Customer) and AML (Anti-Money Laundering, consisting of transaction history analysis) procedures are explicitly stated in the laws of many countries. Usually, when someone wants to exchange cryptocurrency through a “white” exchanger or exchange platform, their transaction is checked by AML tools and, if it is assessed as high-risk, the client is required to undergo KYC—provide their passport details and information about the source of funds. All this is justified as a fight against various crimes, fraud, and even terrorism. However, as we will now see, such procedures can, on the contrary, encourage fraudulent activity.
One of the fraudulent schemes directly linked to AML/KYC is revealed by the creator of the cryptocurrency exchange monitor antiswap.info. When someone wants to perform a crypto exchange, exchangers conduct an AML check of the transaction via third-party services. But the methods used by such services raise doubts. For example, you yourself may not be involved in criminal activity in any way, but if the coins you currently hold were involved in it a dozen transactions ago, they will already be considered “dirty,” and you will have to deanonymize yourself and somehow prove the legality of the origin of the funds.
One of the users of the kurs.expert monitor points to cases where people were simply withdrawing funds from closing exchanges, and these were flagged by AML verification services as stolen. The essence of AML checks was also well described by one of the commenters on the miningclub.info forum: “I sold a bicycle to Vasya and bought a car from Masha. A year later, it turned out that Vasya was dealing drugs and making drops while riding the bike he bought from me with drug dealers’ money. It turns out I am an accomplice and Masha is the owner of ‘dirty’ money. Consequently, will her account be blocked, as well as the cash register of the store where she bought sausage yesterday?”. Furthermore, many commenters there point out that AML verification services may assign a transaction risk without any basis at all, since no one checks how they conduct this procedure.
Naturally, if you fail the AML check and the exchanger does not like your arguments during KYC (or if you simply do not wish to deanonymize yourself), your funds may simply be stolen, or you may be charged a huge commission for their return. As the creator of Antiswap writes, a third of the exchangers listed on the popular Bestchange monitor were caught doing this. But why then do almost all exchangers there have a perfect rating? The reason is that Bestchange considers the seizure of coins due to failure to pass AML/KYC to be solely the client’s fault, and all complaints regarding this are moved from negative reviews to neutral ones, which do not affect the exchangers’ rating.
At the same time, you are unlikely to go to state authorities to complain about such exchangers, as they will likely also have questions regarding the origin of your funds, and thus you may only create new problems for yourself and recover nothing. Thus, exchangers with dishonest owners and employees can practically legally engage in theft and fraud.
The website antiswap.info contains a list of such fraudulent exchangers, as well as a list of those who can be trusted. Of course, among the trusted exchangers, very few openly state their readiness to conduct exchanges without forcing the user to undergo AML/KYC, because many are still afraid of repression from the stationary bandit and publicly report their compliance with its requirements, even if they actually perform no checks. This creates difficulties in finding exchangers that are truly ready to conduct anonymous transactions. However, it is still important to separate blatantly fraudulent exchangers from those who can be trusted with high probability.
