Q. How do you comprehensively destroy a cryptocurrency's fungibility ?
A. By wrapping it in various altcoin crispy coatings and creating a heterogeneous coin supply from a previously homogeneous one.
Time to release CrispyCryptoCoin! A new currency that's an old one with a lovely bitcrunchy coating! And what's just so great about it is that it morphs into dozens of different types (and values) of crypto when it gets out into the field. There's all the colours of the rainbow, soft centred, hard centred, versions that can be pegged against the Euro, the dollar and the yuan. There's offshoots that are auto-swapped for real gold (that's in a vault in the cayman islands) and other's that are automatically hedged again the S&P500. You can mine it, dine on it, drink wine with it and go online for it. Yep CrispyCryptoCoin is going to CHANGE EVERY way you think about money! It'll be all things to all citizens, a true crypto for the people!
