A large number of fraudulent projects have been watching lately and it's hard to do something about it!! Waste of time talking? I do not agree with you!!! First, you gain experience in understanding the cryptocurrency market and the entire blockchain system. Second, you do a good job helping a good project, and third, you get the opportunity to earn some capital in the future in the coins of those projects that you have supported on the way of their development)
I agreed with you mate. We learned a lot in joining bounty campaigns thus it is not a waste of time. Yes, there are a lot of scam ICos these days which makes your efforts put into waste. Thus, the best thing to do for now is to double check the review woth the project and the team of the ICO. But probably sooner there has to be done to minimize these incidents.
