Often see some bounty post, how can I do to get free and have the potential coins, for example, in the bittalkcoin this forum on their product post, what is the request for my account? Activity quantity
So you should join the bounty program, that's a good way to earn bounties coins, after the ICO is end, you can sold them on the markets and of course, a lot of people are earning a lot of Bitcoin because of Bounty programs.
I do not think it's easy to follow a bounty program, because it requires good knowledge in the crypto world to start posting in Bitcointalk forums so you are not considered spamer by campaign manager. If you already know a lot about it maybe you can join in the ICO project.
