There is nothing you see in this world that some set of people cannot do fake or do fraudulent acts for, I don't know if this scenario is conversant in your country but in mine yes. You will see some people telling you they are calling from your banks and collect some certain information and dupe you of your hard earn money.
The sad truth we all should actualise is that there is scam everywhere even in our real world, most people are just too lazy to make money legitimately there prefer fraud, well even in my country scammers does same thing, there call you claiming to be a bank worker and seeking for your credentials to be able to extort money from people. Well this shows that scam doesn't exits in crypto alone it's a thing which revolve round the world, but no matter the rate of scam coins the good and beneficial ones are still up and doing.
