Everything is not so bad. If you just participate in bounty campaigns (Twitter, Facebook, Telegram or signature campaign here on Bitcointalk) you will probably finally get some tokens without any risky investments. So the only thing you'll lose in case the bounty will scam it’s your time.
I think you are right. There are many members in our forum who are very reluctant to participate in the bounty. It's never right. There are still many unemployed people in the world who have endless time. What is the harm if they participate in the bounty and also get paid 25% of the bounty? Moreover, the amount of scam bounties is now lower than before.
Money makes money. But there is only one bounty where you can earn some money without any investment.
