Of course, you have to know what you join. You can or read the technical documentation, or ask in the telegram group because usually when in the technical documentation there isn't enough information, managers or team of the project are very active in the telegram group. Further there is a Head of a campaign. You will see whether the manager has good reputation concerning campaigns. Those managers who have big names, as we know, have only a good campaign as they seriously care for the names and don't want that something destroyed it. And, at last, check the spreadsheet of members. You will know that the campaign will be successful if you with members who are well-known or have higher ranks, than you.

Subscribe to private private chats there is always new and important information.I think that this is one of the best ways to identify and find the right project

To choose a good bounty you must be experienced about cryptocurrency  doing good analysis about the bounty campaign you're about to join in order to earn good money.  Trading through the white paper is essential too and knowing its background

To be honest, it's very difficult to choose a good program right now, since managers put very cruel rules and where there are a lot of people lkshe rules, so it's impossible to earn

Until recently, participated in the bounty only with such well-known managers as Needmoney/aTriz/deadley
Almost all projects collected a lot of money, there is almost no scum ...
But the last 3-4 months to them in the bounty of the company is packed for 3000-5000 people, and payments to the bounty people have become simply ridiculous ... (in the Lendroid company from the manager deadley, i received $ 5 for 2 months in Twitter)

To choose a bounty, you have to check :
website
whitepaper
the team and developer
the idea of the project

after you check all of those points, then you can decide you should join the bounty or not.

I look at the number of participants. If it is a huge and there are people from the ranks of hero or legendary, it already means that the project has attracted a lot of attention. It is unlikely that this would be a deception.

experience they say is the best teacher. with that you really tell the best bounty to participate.

Choose a bounty with a good bounty manager. Someone who has a positive rating, which is proof that that certain manager does not have scam projects. Also look at the project if it reachable or not.

It is very important to read the background about a bounty because there are many which are not very stable. You need to make sure you find the god ones. Also, read what other people say about them
