YES! First, you should research on the project in which you want to join bounty! If the project is legit join otherwise leave it!
Second, look over to the bounty allocation and convert it to the current USD value and current exchange rate for ETH, if the bounty allocation is in ETH as per their ICO token price.
Third, if the allocation is less than $200K, leave it! more than that, the more the better, carry on!
Fourth, if your Facebook or Twitter account has decent fans or followers (5000+ Facebook better, 3000+ Twitter better), you may join their social media bounties. but if you have less friends such as 1000 in Facebook and 500 in Twitter, better to stay away because now it might be a just waste of time.
Fifth, this rule you can apply no matter you have joined social media or not, if you did not join social media then you should invest most of the time in this rule, and earn decent amount of tokens. You can join their content bounties, you may write your content in any social media or blogging platforms such as steemit, medium, Linkedin, minds or telegra.ph. Try to make your own video, you just need to have an account in YouTube which is free, and for recording you may use camtasia. If you are good in translation, you may translate their website or whitepaper in your local language, and earn lots of tokens.
Six, if you are expert in few things, just email to the bounty manager or team with your idea, if they allow, you may join it.
I am also a bounty hunter, I am hunting in Social media, such as Facebook, Twitter, Linkedin, VK, Medium, Steemit and Reddit, Content and Videos.
Hope it will help you! Good luck!
