What is your experience with bounties, which of them get the most profit ? The smaller ICOs with less participants or the bigger ICOs with way more participants ?
Would be good to hear some comments of you, because I wanted to start with translation bounties

Translation campaign does not depend on the number of participants or hard/soft cap of an ICO - generally there is a fixed amount of tokens dedicated to translation services.
The reward depends on the amount of work (the length of white paper, for example) and the greediness of the project team.
A hyped project can pay like $200 for translation of a 30-page WP, while an unknown project can allocate tokens worth up to several thousands of dollars - you can never know how exactly the reward will look like.
