I partially agree with Lucius. However, there are some bounties in the bounties session which may be worth.
For someone who has the experience, maybe the whole thing will not be a complete waste of time, but we know that most newbies have no ability to distinguish between good and bad, and it all comes down to luck. I know that everything in life carries certain risks, and everyone has the right to take those risks.
I just think that is the wrong approach to come to the forum and only do bounty campaigns. After some time many actually realize that they have earned almost nothing, and that they are still a newbie with 0 merits.
