Just go look at Infowars or Zerohedge for 5 minutes. I'm not sure what to tell you, if you come out of that thinking that they're not trying to take advantage of suckers.
If you read Matt Levine’s Bloomberg column (I highly recommend it) then you’ll eventually encounter a point he repeatedly makes about institutional investing: the best opportunities are always right at the edge of comfortable. Hidden gems tend to hang out in the same neighborhoods as outright frauds, metaphorically speaking.
I check ZeroHedge daily, not because I “trust” it as a news source, but in accordance with the principle I alluded to above: the really good stuff is probably going to be hidden among outright conspiracy theories and psyops. Most of the crap on ZH is just crossposts from various blogs anyway so it’s pretty easy to filter through it.
