I think there are a lot of projects which are real, good and has huge potential but due to very low interest by investors the project did not get the soft cap or hard cap and then the project extends its IEo or ICO and after due time again it not get the keen interest by investors and at last the project become scam. And the most affected by these projects are bounty hunters as they always do there best to promote the project but when they did not get any rewards then this was the most hurting situation.
there are still many real projects, but the concept they have is sometimes not good enough which ultimately makes them fail to get good results at sales and make them fail when starting the project because they do not have good funds. quite difficult for new people, and sometimes even experienced people can get caught up in fraudulent projects so the best way is to be careful when looking for projects, and don't forget to always look for complete information
