> half a trillion USD is a tiny market
What?
What is the market cap of our two-animal store-of-value ecosystem?
(Unless you're an economist, the answer is not "Two million dollars.")
On the other hand, if I then went ahead and sold your cat to some outside party for $600, and you sold my dog for $400, we could reasonably say that the market cap is ~$1000.
Pretty much any 5 of the Fortune 100 has a market cap greater than 500bn, 500bn is a fuck tonne of money but compared to the aggregate size of the market it's pretty much bugger all.
