Just finished my second campaign on bountyhive and I was a little disappointed for the second time. The payment was really low.
I'm going to wait for a few more campaigns, but based on the current results I would not recommend them.
If there is a limit to the amount of tokens that are going to be given in the bounty campaign and you are doing the same that everyone is doing it will be very obvious that you are going to get very low payments, at this point it seems to me that is more profitable to look for your own bounty campaigns, maybe it will be a little harder but you will have less competition.
