Yeah, I agree with you. Or to be more precise, 90% of current ICOs are scams.
Maybe more I guess, TBH, I don't trust at ICO at this stage anymore, why? because we have an IEO, the new model which is more safer for the investors, so why would we still go for an ICO.
Therefore, when you participate in any bounty campaign, please review the project information carefully. Not only did you not receive the reward, but you might also have helped the scammers.
In the past, participating in a bounty on an ICO project gives real good payment because the market was bullish, but things have change a lot, now, we can't easy make good income from bounty, so maybe we should also consider to find another source of income and just come back when the market is bullish again.
