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.
I believe that the states knows exactly what to do, but I see their silence has deliberate act to frustrate cryptocurrency since they are not in support of it and would also not want to legalize or regulate it.
The SEC knows everything that is happening within the cryptocurrency space but because of their own STO, they decided to keep mute, so that investors will be forced to drop the idea of ICO back to STO, but I am glad that we have lots of individuals who are also crypto lovers and are working so hard to see how this issue of scam can be eliminated, people like Binance with their IEO, and I believe that we will still have other ideas later on.
