There will be no such success in bounty as it was in 2017. You need to accept that. Now you need to choose projects for participation very efficiently and do not put high hopes on them.
This actually true. Bounty is dead since 2017, only 1or2 bounties that really success out there which is really small chance to get one and the rest are scam and not worth bounty. It's better to move on from bounty or find bounty that only pay with bitcoin, ethereums or other good alts and directly paid weekly or monthly. It's more safety than need to wait until the bounty finish which take months or even years.
