Participating in to bounty program should be done after lots of crosschecking and verification. I'm not sure how many people are valuing their hard work that they are going to put for a campaign still I do see many scam projects are finding their success only due to the people who are all ignoring those crosschecking.
I'm always not preferring to contribute in ICOs for many reasons but the prime one must be I should not support scammy people. Instead of looking for making big money out of ICo, I am more careful on not supporting scammers, it is kind of being more conscious against scammers.
I am also finding lots of people are randomly participating in to bounty programs without checking that where they are going to work and for what people they are going to put their hard work. They simply check what are the rewards and not even looking for what is the assurance to get payment with them, but simply enrolling themselves and then start wasting their hard work. I agree this must be the reason why scamming people are always enjoying in ICO industry.
Not just with strange projects, we always must need to be more careful while choosing coins and ICOs. Because this is how, we may protect ourselves. Unfortunately many people are being careful while spending hard earned money but they become lenient when they are putting their hard work. They never understand their hard work is another form of money. But, they are ready to risk their hard work.
