Too bad you only say quantitative value about this forum. Why should you rely on income? actually when quality can explain everything and there is no need to state everything by participating with campaigns etc which makes it as if this forum has no other interest. See that in fact it will follow when we have quality, if relying solely on revenue means you are not empowering the purpose of the forum for much more useful discussion. There's nothing wrong with that, but there's a lot more valuable knowledge on this forum that you can't discuss out there.
As a suggestion, take a look at their project which seems good for you research.

I only gave a little explanation to him about free work and related to other things, of course I directed him to more positive things and it also didn't mean I relied on income. I keep the name of the forum as good as possible to everyone and not even just colleagues, I understand that there are more important things in this forum.
back to the main topic: I will research and review every investment advice including the link you provided.
