Bounties provide a way to increase your holdings in a particular token or coin. So, of course if you believe in the tech and the coin then you should do bounties and see how it goes.
It is basically a way to earn tokens for your time and effort rather than paying for it - whether this is worth it is totally up to the individual.

Bounty hunter should take seriously the campaign because this is opportunity of a life time and you better not to waste the opportunity of having great coins in the future. I consider bounty campaign as one of my job so I really have to perform well so I can be qualied for all the requirements of the campaign and of course the rules and regulations of this forum.
