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.
I think juicy and bumper offer promised by those scam projects usually entice newbies, unfortunately those newcomers are usually very greedy and carried away by 10X profits thus swiftly invested their hard earned money into those fraudulent projects which later turned scam, infact there some of investors despite the overwhelming evidence that some those projects look suspicious unfortunately still went ahead to invest in them and due to lack of crypto market not regulated many of those projects are having a field day.
