So maybe its still a bit too early to tell but it looks to me like if you want continuous traffic and nice volumes you have to constantly add new campaigns and watch your keywords/bids. This isnt a big problem if we were talking massive hits and potentially a lot of profit. But so far, to me, it looks like it might be too much work to make 100 bucks profit.
