first off all you are now Jr member. its not good rank for joining signature bounty campaign. Signature bounty is now hard to find out.why? because daily a lot of campaign coming in this forum and we cant find out suitable bounty program.also a lot of scam/fake bounty announced now a days.so why legit good bounty are rare now a days.
Hmm... you are right. I have seen threads here which accuse ICOs such as Impressio and Uchit to be scams. And they have been flagged as scams by some of the ICO review sites as well. I feel sorry for those users who participated in their bounty campaigns. All of their effort has been wasted.
