Why are you all so worried about stupid investors putting their money on a scam? It's their money. (Hopefully, at least! If not, we should be concerned about something else than what they are buying with it...)
I'd understand this reaction if this was some well-crafted scam that's easy to fall into.
But everybody already knows this is a scam. By just Googling "uBeam", the first result page shows several disturbing hits to severely criticize it - including, but not limited to, Dave's debunk video.
I'd assume an investor at least uses 1 minute to Google the name of the company they're going to invest in.
And, I'd assume a sensible investor would check out the huge alarm bells going off everywhere, when they do that 1-minute Googling. You know, dig a bit deeper. Use $200 to get an opinion from an engineer consultant first. Things like that.
The fact someone invests in this kind of totally obvious and already well exposed scam shows they are either complete idiots, or just have too much money and they don't care about spending it in random scams the slightest.
But this is, indeed, interesting to follow
