so the bounty would distribute after the ICO end?
would it distribute before trade in platform or after trade in platform?
waiting your answer ,thanks

Tokens will be distributed before, Vibe will be live on exchanges for October 1st, giving everyone more then enough time to redeem and distribute to the people who participated in our bounty program
Great but exchanges in plural? I thought that exchanges decide themselves if something is accepted or not, do you have any confirmation about the time frame from any specific exchanges?
there are different exchanges. on one it's easy to listed, and on others it's not so easy - Bitrex, for example, is difficult to get into recently, and they also have a condition that is not allowed to announce such an event in advance..
but I think with time, of course VIBEHub will be added to the best exchanges

That depends, if they already have deals with exchanges, they simply could ask for a date for the token to be online, while being ready for it days before, having a date means that the deals are set, and exchanges will start trading the 1st of October.
i think at the begining they will list the token on some medium exchange because big ones like bittrex are hard to convince and it will take some time...
