The banking system has always used this pretext to cast a shadow over decentralized cryptocurrency. They already need to come up with something new, however, apparently, they have no other arguments, and the old arguments, which in fact do not correspond to reality, were again used.
Previously, both in Europe and in the United States, relevant studies have already been carried out, and they all showed that Bitcoin is used for criminal purposes only in a few percent of cases. Cash is used much more often for this, so they should pay more attention to their fiat. Moreover, I think that this is not relevant at all for El Salvador.
