Of course, you can not be jobless and you can also participate in bounties (only if you have main job). Just be careful to pick a bounty so you won't get scammed.
Yes. I am agree with you. For sure some students and employeed person is here to earn money. We can not be jobless as long as we are active in seeking for a campaign. Lots of campaign will be found here but few are legit. If you are years in this industries for sure you are aware on campaigns that scams and not just be observant.
