Negative, I haven't looked further into it. The case Luis makes is a speculative and political, not necessarily about the technology. For years I knew that XRP was meant to be the bank coin, so I stayed away from it. I missed an opportunity because of that, but I don't really regret it.
I was watching a Jim Rogers interview the other day where he said, it's important to invest on what is going to happen - not what you want to happen. So Luis has a point.
