A few general tips for noobs doing bounties (I'm actually a noob at bounties myself):
1. Do projects that interest you or that you support. Don't try to do every campaign.
2. Look for bounties that you can do. You don't have to do everything. You can do just the Twitter bounty if you want, or you can just do Facebook. Focus on what you know you can do.
3. If you want to, look to expand your bounty hunter possibilities. If you don't have a Twitter account, open one and start to build up your followers until you have enough to do bounties. Post more on this forum until you rank up to at least Junior Member so that you can do signature campaigns. Plan ahead. Think about what options you would like to have 3 months from now or a year from now and start working toward that.
4. Read the bounty announcement - all of it. Know when the campaign starts and ends, who the campaign manager is, etc.
5. Follow the directions for signing up, submitting reports, and getting payment.
6. Submit or post your stats regularly and keep a record of what you have done and submitted.
7. Periodically check the spreadsheets for accuracy. Usually things go fine, but sometimes stats won't be updated or there may be an error. If there is a problem, ask the campaign manager to check into it.
8. Be patient. The campaign manager is busy and will update your info when they can. Post any questions in the bounty thread and wait for an answer. If you don't get a response, ask again. You can also PM the manager or ask in the bounty chat channels such as Discord, Slack, or Telegram.
9. Don't lash out at the campaign manager. If you are denied participation in the bounty, ask to fix or update the problem. If that's not possible, move on. The campaign manager has rules to follow. Getting too angry with them won't help you or anybody else.
10. Have realistic expectations. Sometimes ICO's fail, end early, or actually end up being a scam. In these circumstances, you may not get paid anything. There's usually nobody to complain to. Don't get mad. Move on.
11. It may take a few weeks before you are paid. They will usually give you a time frame, either in the bounty announcement or it may be announced at the end of the campaign.
I'm sure there is more, but these are at least the basics for doing some work as a bounty hunter. Enjoy, and good luck!
