Hi!
I have been participating in bounties for various coins! It really depends if you are participating for a long or short time profit. (ergo get big $ or a big chunk of coins)
However, there are 2 special candidates i always participate since they always give me a nice chunk of their coins

.) Deviantcoin
.) Dinastycoin
I am a Holder so actually this is my style of bounty hunting. If you are going for a short time profit, i would just check the links that have already been posted in this discussion
If you have any tips for people like me , please post it and i will consider participating
