Listen mate, there lot of bounty campaign here. Im sugesting you to chose wisely, try to join a campaign managed by some profesional and experienced manager such as Sylon, Needmoney, Blockeye, Hotachy. Also if the bounty campaign require you to do KYC just do it as long it worth to do, but if they ask you to pay, just dont. i mean 0.1 eth is not small money for some people right ? We help them advertise by posting here or do retweet and tweet at twitter also like and share at facebook.
I used to join some random campaign when i was junior member, but now i only join good campaign, yeah we will never know for sure if the project will be scam or succes in the future, but we can reduce the risk by only taking good campaign. So follow my advice and be wise mate. Good luck for your next campaign.
Your advice is very amazing,great people learn from the experience and that's what you do.I am a newbie and still confused and analyse the bounty that good but from the advice you give, give me motivation to always learn and proceed.Thank you,hope in the future i can be good and great bounty hunter like you and other.
