I don't think the Bounty program is over.
Of course, the ICO market has died a lot, but I think the Bounty program will continue until a new marketing plan is released.
Or if there is a new marketing plan that I don't know about, please let me know.
If what you mean is profitable, there's hardly anymore, out of 10, maybe 1 or 2 are a legit campaign, ICO is dying there's no doubt about it, but bounty campaign is not for ICO anymore there are a lot of projects that are already in the market, that's still doing a bounty campaign, there's nothing wrong with bounty campaign and it will stay on, what harm the bounty hunters are the scam projects that continue to lose investor's confidence.
Bounty campaign is not over during many ICOs project still running looking for their investor, when many ICO still active and give feature for investor there are have chance for bounty campaign to get reward by joining their bounty. When bounty campaign is over? I think when many ICO have failed and investor not interested for investing with ICO anymore.
