These days almost all bounties do not pay well as before because this market condition. Most of ICOs fail because of this market condition. But it will change near future.

We can do bounties with lots of social media platforms. But now work with twitter is so much difficult because they ban lots of bounty hunters accounts. So, we can't use twitter for bounties. But we can use facebook and linkedin platforms for bounties and if you have bitcointalk account with a rank of jr member or up you can do signature bounty.
