In my opinion, Bounty performance in terms of budget and payment to hunters has been on the decline for the past 10 months. Out of many campaigns that I have participated in (for the past 10 months), only about 5 campaigns made payment in the range of $10 to $40, while two campaigns paid in the range of $200. Most of the payments are less than $1. On the average, for every ten projects that I have participated in, five ends up being scam, or will have one issue or the other despite doing some research on the project before participating.
Nowadays have many bounties campaign increasing drop bounty budget payment for participants, usually each bounty allocated about 2% until 5% from their coin supply distributing to bounty participants. Last two years all bounties have allocation budget for bounty reward with stable coin values under $10,000 but distributing trough altcoin bounty project, when price listing in the market drastically drop reward and each participants get not higher above $10.
Beside many project not reach their goals with pre sale become problem why less budget or reward distributing for bounty participants, I think most important with project advertising become success and get higher reward later with bounties campaign.
