Every day, a large number of bounty campaigns are launched, but about half of them are fake, and the majority of them end up scamming both investors and bounty hunters. I'm not sure what the bounty was like in 2018, but it's definitely not paying like it used to, though there are a few managers who bring in good projects and are rewarded significantly.
However, getting a good project in bounty currently is a matter of luck.
Bounty campaigns had not been rewarding like before thus any participant who promote any project now should not anticipate any bid reward, crypto market is presently awashed and flooded with many fake and scam projects which are well packaged such that they might look like a real project whereas are fake, bounty hunters need to intensify or channel their efforts on other alternative means and ways of earn cryptos other than bounty hunting because it's a big disappointing after several weeks of promotion hunters wouldn't get paid or paid with a small reward.
