Last year, you can easily get more than $200 in rewards through bounty, and the income is very stable, but this year's bounty is very bad and most of the activities won't be rewarded.
As of now is hard to earn money in bounty campaign and as you can see the bounty will run for couple of months and you will earn low amount of money and sometime you will earn nothing. This year we have bad experience in bounty and I hope this coming 2019 there will a lot of good bounties.
