This requires not only the strengthening of supervision by countries, establishment of a regulatory ico department. but also investors need to improve their knowledge of crypto,when investors have certain knowledge of crypto, those scam icos will be more and more seen through by more people.
First of all, it is the mistake of an investor if they are getting scammed on the platform that they are putting their money into. In that case, blaming the project is not bad at all but the point here is that, why would you be scammed if you are doing your best in order to maximize your profit at the same time, making a safe move in the market? I am not saying that taking risk taking was to be avoided in the first place.
