Bounty hunting is all about taking chances now, if you are not ready for a deep research you will miss the good projects and go after the bad projects thinking they are good, deep research can safe you from making bad decision
also dont forget that participating in bounty also has risk , what is the risk ? The payment they give to you there is no guaranteed value you might recieve high rewards or low rewards depend on the project you promote. Researching is big help for this but we all know that even you search about the project we will never know if the token will get value.
