every bountymanager is differrent and also every ico-team has their different ways to end the bounty , sometimes you get your coins right after ico but there where times that i waited 6 months or more
Yup, I agree with you, every project has different progress and different problems from one another this is why some pay faster while others pay a bit late and some pay way long. But nevertheless, if you really did your own research and are pretty sure that you have done it right and joined in a legitimate or credible project that hosted the bounty you're in, then you shouldn't be worried. Not unless they do not update anymore.
