There are many scam projects in the crypto market. In order to make profits and attract investors, many new projects will deliberately exaggerate and say that they will provide investors with the greatest profits. But over time many projects will turn into Ponzi schemes, will cryptographically prove that what they say is false, and always end up disappearing from the market as fraudulent.
That's right. This strategy to attract the investors are not new actually and those who will likely fall in this trap probably didn't conduct their own research before investing their hard-earned money.
But I think most of us also experienced to invest in projects with too good to be true offer and it's because of our greed when we're still newbies. The good thing is, we learned from that experience and aware now that these projects are not worth to invest in.
