It is true that counterfeit money is a form of fraud and we cannot deny that it is a part of our life, we sometimes face it.
Scams are everywhere and I think there is no way to stop scams in the cryptographic world and even in the real world.
Currency is indeed created but cannot develop so that it is eliminated and is considered counterfeit, it can be a worthless dead money.
In the real world there are many scams, so for crypto money, there are also many who cheat and have no value, so it all depends on us how to manage it.
