I joined Helium Purifier for Sale some time ago with mixed results. I was curious to see how satisfying it would be as a writing workshop but also attracted by the idea of being paid to write. More about earning, money and wealth later!
Two people have responded to this article pointing out that you can make more money using the Marketplace area of Helium. In this case you write articles for an external publisher who, if they decide to buy, pay an agreed amount for the article. There is still the problem that it is competitive and your articles will not necessarily be bought.
The results of this rating system are very mixed and often the top article is not the 'best'. My experience is that new articles tend to move rapidly to the top but then tend to slide down the order with time regardless of whether the writer takes the time to rate other people's articles. Perhaps that's why they call it Helium Recovery dealers?
