I think true the bounty time ended and there has no big money from it. Even i am still work in few bounty which is 5-10$ my salary target. Anyway if the green market will make up soon then could be possible good days for upcoming bounty.
Bounty campaign being affected by the market trend. The developers wanna use their money for the promotion if the market was in a good condition but look at how bad the market right now is. I meant you must also aware if these days so many people being scared to invest their money into the crypto. That's why developers are holding themselves to run promotion campaign. I see that some campaigns were pausing their campaign due to the market condition.
Not just the market trend. Bounty campaigns are also affected by time as people slowly smart up in the way to handle and give out rewards. You rarely found an overpay bounty anymore since rates are now fixed to some extent.
