I'm least excited about Wall Street buying into Bitcoin (also ETFs and other BS), it's money for the people, not money for money bags, but the technology is such that anyone can own bitcoins so obviously money bags will have the most of it.
I look at it as kind-of a trap. They can own more of it, sure. They just can't print more of it.
Doesn't stop them from trying with all sorts of derivatives and shit. But I do hope it all bites them in the ass, so "trap" sounds about right.
