1. Always read the rules and digest it.
2. Try to ask some questions on the rules even though you understand but to be sure you are doing the right thing.
3. Always crosschecke your activities if you have followed the rules. Check your entry again... Something might be wrong with the network without your awareness. Then, you will realised that you have missed something you thought you have done.
4. Don't desert the support channel, engage the admin and by going their once in a while, you will realise that your experience will increase rapidly, this is because, you will have asses to different challenges and solutions.
5. 24hrs to the end of the bounty or AD week, go back to check your entry, you might have missed something.
I this no5. Was the reason why I missed last AD, I have done everything except that I did not retweet one of the official tweets.
I hope this is helpful
Problems with bounty hunters nowadays is they are too lazy to read the rules for the airdrop.
Always keep in mind that every week there's a possibilities of new rules being introduce by the staker team. Like last week many didn't register in the forum and they got skipped.
This is the experience that will help them pay more attention in the next round. Not only the airdrop but also the ICO must pay attention to the changes in rules.
