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?
If you feel that the project you participated in won't last long, you sell it. There are factors where the projects last like continuous development. I had this coin from the bounty I participated before called $CHSB also known as Swissborg. I sold it too early until it goes 5 figures at ATH. It really depends if you apply investors mindset on the bounties you participated in.
