Do your homework, most of these cloud mining operations are run on a Ponzi type model, so the last people invested, will lose their money. The golden rule : Bitcoin is not a Get Rich Quick Scheme.
I agree with you, it belongs in the beginners section.
However, nobody mentioned any cloud mining operations...
Why did you mention it?
RoughLyfe mentioned it here. And I gotta agree, cloud mining is no longer profitable. The only cloud mining which is trusted by many is CEX.IO which currently stop operation due to low Bitcoin price.
Sorry, I didn't see that.
Cloud mining was never profitable.
They are all (that I know of) ponzi schemes.
If it was profitable - for the buyer - then the seller wouldn't sell it, they would keep the profit for themselves.
