Will Trace's proofofkeys affect anything one way or another?
I am curious and leaning toward participation.
I think it will. I think we are already seeing fractional Reserve type situations at many of the exchanges. And if people demand to take delivery of their Bitcoin and actually hold their own keys not only could this have an interesting effect on the price. But it would improve the situation as people start using Bitcoin the way it was intended to be used instead of sort of commodity that can be traded on paper.
That was my point when talking about derivatives (future) settled in fiat vs. physical. Old schoolers might be used to paper - and I believe they are, after reading gentlemand's and bitserve's replies - and likely a few others who didn't feel like they needed to chime in since the point had been made already.
My take is: once crypto derivative investors get spoiled by the real deal, they won't be tricked into paper coin anymore - new school or old school alike. And once physically settled derivatives start to be seen more and more, they will drive paper stuff out of the market - or at least eating into their market share.
