Work time is needed for a bounty campaign to be successful if what the manager ask you of what to do I really think you would need to do it Or this particular things are needed in order for the ICO to make an announcement or advertisement they truly needed so many investors would know about them I really think it is necessarily needed that is why they are establishing bounty campaigns for you to work in a recommended basis they needed, And sometimes managers would extend the campaign depending on how they want it, So bounty campaign will certainly will take much of your time, And joining the bounty will sure need a lot of patients and determination that at the end of it you will get a worth while pay that you deserve.
Yes, I agree with you and I think if these is properly done, the bounty will be successful because if the activities are not completed and there is no good marketing and manager, the campaign will take time to end and the project will also take time before it can be launched. I believe signature also help in the success of a campaign.
