I know crypto and I know comics, so I guess I have to check this out...
OK, I don't want to be another naysayer but... This is a very effective way for the operator to sell comics at a price of their own choosing.
Correct me if I'm wrong, but after a quick read it looks like it works (or could work) like this:
I buy CBC from you with Ripple. You sell Ripple and buy comics (from yourself if you like, at your valuation) to add to the CBC collection. My CBC now has a real world valuation of (value of collection) / (number of CBC in circulation).
Now, that COULD be operated in a way that is 100% equitable, but it COULD also be operated in a way that is downright cheeky
Given the long history of 'scamcoins' I expect most people will assume the latter. It helps that there is a store with a physical presence. If this were to have any chance of success it needs total transparency, and I do mean TOTAL.
