Most of us taking part in bounties want projects whose promotions are briefly around 4 weeks but want to get a large payment.
When in fact projects that are long promoted are more likely to pay big, because developers have tokens sale time relatively long
time. Therefore we must be more patient if we follow the bounties, because good projects will promote longer so that token sales
can be maximized. That way can pay bounties participants in large, so it is equally beneficial.
