Fraud in any state is considered a crime. However, there are a number of difficulties. ICO fraudsters collect money from investors all over the world. The first difficulty lies in the fact that the local police cannot do anything directly with such scammers. You must first contact the police of the country where these scammers allegedly were. This may be the case if between these countries there is an agreement on cooperation in law enforcement. If not, the police must act through diplomatic channels. All this takes time. Further, it may turn out that the scammers were not in that country, They could even migrate to different countries. In general, it is quite difficult even if the police work quickly. In addition, crimes related to the Internet, it is very difficult to prove.
