I want to earn extra income through bounty hunting and hopefully you can share good projects worthy joining for in signature campaign.
There are always some good bounties in Altcoin section to participate in. If you are active in Altcoin section you will find it yourself. You can participate in signature campaign managed by Hhumpuz, TheAndy500, Bounty Detective because most of the time they managed good campaign.
The first name you mention is BM which is not only reliable but fast enough to handle all the bounties he hold, there is one signature campaign that pays with altcoin and rates high enough but because the OP is only a member maybe you can find another bounty, which He is still managed.
Or Op if you are reluctant to wait long to be able to sell your bounty results, you can choose a project that has been listed on the exchange so when you get paid you can immediately sell it.
