Bounty gives you an opportunity to not only to make an extra money from the tokens but also a chance to know more about he ICOs. I use bountyhive, but I would not suggest making it your primary place to go for new bounties to join. This forum is and will always be the best for that.
that's right, you can learn while doing bounty campaign, this forum is full of information needed by anyone, there's a lot of information provider that is being shared by any individual.
