The video you posted features a guy talking about a ponzi scheme, meanwhile he's trying to sell t-shirts and coffee mugs and says that "shipping is only $3". Who is trying to make $ here??
I don't doubt that people are making $ off of Q, but again, Q doesn't tell people where to go, or who to listen to. They are just passing along information. More and more people are turning to the internet and alt media for information because they are waking up to the mainstream media's lies. This growth of the alt media did not start with Q, nor will it end with them. I don't think it's accurate to blame people for making $ from Q when there are literally 100s of places to find their posts. If there were only 1 or 2 sites you HAD to go to, and create an account, to find the info, then i'd be suspect. This would also make it easy for the govt to track who's following Q. But I can literally go to a different site every day of the year and find the same info. In other words, I choose who to give my "ad traffic" to. Q doesn't control this, nor does 8chan. If people visit 8chan's site, so be it. But they don't have to, so I don't see the Ponzi scheme at all.
Finally, if Q is fake, then Trump's twitter account is also fake, because the POTUS has directly and consistantly confirmed many of Qs posts, days and even hours later.
