Bounty campaigns will exist as long as advertising is needed for the development of the community and attracting new customers, I think for bounty hunters there is still a chance to make a profit, only in this market it will take longer.
No, bounty campaigns will keep on existing as long as the owner of the forum allows them but if at some point he changes his mind then you can say goodbye to bounty campaigns so all of those that are depending on them to get money need to look for something else to do so when that happens you do not suffer that much the lost income that you will not get anymore.
I supported what Btcmaster said because the purpose of bounty campaign is advertise the project, gain new investors/community support and increase the current circulation token/coin. But, it unfortunate that some people abuse the benefits of bounties. However, forum moderators won't stop bounty and can only tighten the terms and conditions.
Guys, you really choose the right things, because advertising today is needed not only by ico companies, but will also be needed by other types of startups. But if we talk about the difficulties involved Bounty companies On bitcointalk, then you should take into account the fact that today there are other forums with similar activities.
