I just want to know if you also experience what im experience that you assuring the given date of ICO will be move in next 3 months and one of the bounty I've joined was also almost 1 year but still no exchange happening and they are always keep promising. What is your feeling regarding of this happening?
What bounty are you referring to?
Worst case scenario will be for you to open up a scam accusations against them for not fulfilling what they should have been done for 1 year.
Of course, I will be disappointed for not getting my rewards from that campaign. You work hard to promote them and now what? Nothing. That's the risk in bounties though, there's no assurance whatsoever that you're going to be paid in time.
