basically they are not going to pay bounty participants right? because the owner of the ico decide to cancelled the campaign, for sure many participants will be complaining about this. . well we do not have any going to do about this except to accept.
It's a pity, but i don't care
And what to complain then? It's always done, and it's normal. For example, when the tokens are not collected the required amount on the sale. In any case, even if you complain to the sense of it all will be very little, most likely you will not receive any money for the help in the advertising company.
