Very often, governments start banning things they can't control.  First of all, cryptocurrency is banned due to the fact that they will not be able to control the income and expenses of citizens, and, of course, some points in criminal activity.  But there are such crypto assets whose projects are aimed at making business easier, such as the CRATD2C project, where the interaction between the brand and the consumer is implemented.  In this case, the state will not be able to do anything against the project and, accordingly, against the crypto asset.
