What is the recommended time frame for a bounty campaigns?
maybe 3 months to get the maximum stakes from the ico project but I suggest you choose the project carefully because there are too many ico scam projects
Now the bounty situation is risky, first they cheat too much, secondly they have too many people involved. This will make it difficult for us, so I think the choice of the bounty campaign should be careful not to waste time and effort on the fraudulent ICO project.
