I personally just read a little white papper, I prefer to understand the roadmap and see the team working in it, and besides that a good community is also very influential on the success of a project

Nope, there are many factors that can affect our decision.
Such as the amount of community members, the hype factor, the MVP, and of course the team behind that project.

if to choose a reward with a large fee it is better to join the signature campaign ..
gift signature campaign coins that can be greater than the gift of the other

When you're choosing bounty try to review the attention which it draws and think if it can raise softcap.

I would recommend take bounty programs with lead amaze team and token suit, also you may check all bounties with belong to bancor network platform or yourself ICO's rating

i mean besides the whitepaper and team bits, check on the share of the coins given and how much u wld likely get (based on rough approx of participation rates etc.) ...to see if it's worth ur time. the variance of reward for the same effort is very big.

Find the bounty that the bonanza manager really does. or have managed successful campaigns before. That is the simplest choice without having to think

Research, Research , Research this is what you need to do in choosing a bounty, Because you dont want to end of exerting.time and effort and it will just turn out to be a fraud so better research (check road map , whitepaper? team and the bounty manager handling the bounty). But I would recommend to you the bounties of Amazix, Sylon, Wapinter , Blockeye, Aerys, Atriz, Bountyhive (ColorlessK) and Deadley. Sure and legit ICOs and good and trusted bounty managers.

It is very difficult to choose a good bounty compaign. Only experience can help in solving this problem. Undoubtedly it is necessary to get acquainted with the program and the idea of the project in detail. You also need to get acquainted with the team that is going to implement the project. Non-serious commands and ideas of ICO are visible to the naked eye))
