Yes, cryptocurrency fraud has now become a serious global problem. It arose due to the fact that states are very slow to respond to the emergence of cryptocurrency and its regulation. In cryptocurrency now large sums of money are concentrated and this attracts fraudsters. Fraud has always been a criminal offense, but for so many years the government has been inactive with respect to cryptocurrency fraudsters. This is especially true for ICO projects. So far, only individual countries have prepared bills to regulate the activities of the ICO, but their adoption will take some time.
