Yep, I had the opportunity to show Peter my
Shire Silver cards a year ago but didn't bother because he's pretty clearly stuck in traditional investment thinking.
I do like the combi bar idea, and had tried to do something similar a few years before these hit the scene. I just couldn't make it work economically, and it doesn't really make sense as a currency. Its a kind of a cross between an investment and a OMGTSHTFWTF temporary currency for a scenario that isn't really likely to happen.
That said, this does seem to indicate he's learning and will eventually get on board. Its just going to take some time and some profit incentive.
