Update 5: Bitcoin Conference Miami
I had a change to talk to the team from Kraken Exchange. They seemed very receptive after explaining the tech (thanks to JustaBit for helping out with the initial conversation starter). I have the CEO information that I will follow-up on when I get back home early in the week. Peercoin did a great job of presenting their case, there were people in the Kraken eco-system that were already talking about it. Nxt was an easy transition talk with PoS.
Kraken team were great to talk to.
