This is sad but true that altcoin bounty hunters are almost alone in this forum! No one is here to help you to find a better project to promote! But look at BTC paying campaign! If a BTC paying campaign launched, many Hero, Legendary member starts investigating hard! When they find anything suspicious they tag the bounty manager and keep suggesting people to not promote project! Even they can't wait even one week! For example, BestChange launched Signature and Social Campaign, I got accepted in Social and received payment, but many high ranked people tagged the manager because he did not go through Escrow! They did not give them even one week. Though Bestcahnge got a couple of red trust because of suspicious activities, I have no problem with that!
But look at the altcoin section, no one is here to support you to find a better project, everyone keeps suggesting research yourself, even if your well researched successful project not paying you, still they won't support you! So, from yesterday, I started thinking that Altcoin bounty hunters are very alone! Some guy is working to catch scammers but no one is here to suggest you a better project!
Bounty hunting is no more profitable. It is better to avoid them except the signature campaign. Most startups are failing to generate funds through ICO's or IEO's. So no one here can guarantee you that joining a particular project will be good.
I am not sure about what happened to the Bitcoin project that you are referring to in the first part but, I am associated with a Gambling bounty campaign that pays me in BTC and I have never faced any issues from any of the members in this forum and niether the bounty manager of this campaign.
