This is one thing thats why i didnt participate a bounty that took 3 to 4 month. Because you cant tell if the ico is not scam except to those professional who know the scam and not scam. So it will be good if you participate in 4 to 6 week bounty
Actually you can easily check it by yourself by visitting the project website and check who is the team behind the project and how much is the token sold on the sale. Join the telegram group too, look at the activity on the group, if no one chat and only people joining telling "good project, etc" and no real talk then you must be careful.
absolutely right. actually, we can control yourself if understand the road that must be traveled. analysis of various stuff is things to do. much of the bounty said it best if not viewed with certainty as of the team, whitepaper and telegram it will be very prone to falling into this scam and hole a lot going on. Although it was a long-running bounty I don't think it will be a problem too.
