If you do the same kinda research about FBA you will "get it" too and you will know that PoW is useless.
You probably wont make money form that but still I hope you dig into it. I myself saw "the beauty" in bitcoin once and later saw it in FBA again.
After all it solves the same problem just in a very different way.
There are FBA coins out there so people who want can trow money at something an maybe make profit if they gain value. But its not new so who knows how early people who join now really are.
Can't compare it with buying bitcoin at a few bucks that's for sure.
