$0 so far. Simply because I'm not participating in bounty campaigns. And there are several reasons why.
Signature bounties - now I'm participating in signature campaign which are paying in BTC, so I don't see reasons to participate in signature bounties for tokens.
Social media campaigns - I'm not planning to spam my social networks with ICO advertisements. Offcourse, creating fake profiles for bounties may be a solution, but again, FB and Twitter now become strict and they often disable accounts which are spreading spam, have fake friends/followers and etc and then asking to provide ID to unban account.
Translations - I've never saw ICO which ask to translate something to my language
Youtube campaigns - I don't have skills to create nice videos.
Article bounties - to make good and interesting article about project you need to have lot of free time. I don't have enough time to do that.
In general, choosing a good bounty is almost same thing like to choose ICO worth to invest. There are so many bounties currently and we need to make research about project before participating in bounty. Otherwise, after hard work you will get only some worthless tokens. Sorry for being a bit off-topic, but I answered your question
