since 2018-2019 almost thousands of projects have ended in fraud and many tokens have died or no further development.
but I think there must be other reasons why the project ended in fraud, other than project funds were not collected according to the specified targets or project funds were taken by the team.
I assume that the developer and prize manager work together and intentionally promote fraud projects for investors. sorry no offense!
Certainly, this fraudsters or scammers works deliberately from the beginning. They try to deceived everyone in the end, but at the early stage of the project, you won't notice a single thing because they know what they are doing. This can be seen in 2017, when the whole hype started, lots of project with the project of this and that and one day they are all gone with millions in their pocket. That is one sign as well, when there is no development from behind, they will just post something on github to show, entice investors and be gone when they have collected the money.
