I was joining bounty from year 2017 till present i have experience joining different signature and social media campaign with good earnings and there are also campaigns that is not profitable and sometimes there are campaign that doesn't pay, because the project does not reach the hard cap when they launch ICO, most of the projects pays token that is not listed on exchange and we need to wait a months or maybe a year before we can sell our tokens and get the profit and sometimes we also buy tokens from the good projects that we promote and hold, can we considered the patience of the bounty hunter same as the investors patience?
at some point i agree with you, because bounty hunter also gives value to community, they spend their time to write article, making video, keeping good engagement to their follower ( twitter, social media bounty ). and also have a chance to not get paid or lost the time + work investment. investment is not always exchanging something with money. when we exchange our time to something it is also investment.
