About earning from bounty, this will not definitely produce how much income is obtained from one project, even participated in many projects the income will not be certain. For now it's better to join several projects, maybe you will get paid from one project and not all projects will pay with certainty. Sometimes we can not determine a good project or not.
basically you must to keep trying even though not all projects will pay. being a bounty hunter won't make you lose money so whatever income you get from the bounty is you should be grateful. don't expect you will to get rich quick just become a bounty hunter and get money from bounty because that won't be possible.
you can loose here but not money , its effort , time , patience and other traits but yeah we must try and try until we succeed. bounty can make us rich too , before there are many good and high paying bounties , lots of hunters said they bought expensive things like car , house , etc but yeah we still must be thankful whatever amount we get from a bounty rather than complaining because blessings will get turned off at you . instead of getting more blessings in the future , god will be dissapointed on you and will teach you some lesson .
