If you see someone getting scammed on the street, like at a tourist trap, wouldn't you say something? Because this is the same situation, and why it bothers me.

It's literally a scam. People are throwing their real dollars into the BTC market because they were sold on vague concepts and bullshit viral articles like in the OP.

Maybe it's the investor's fault for being dumb and not doing their homework? Sure, so long as they weren't mislead, otherwise they're victims of a scam.
