Not sure about other places but here is a case for Austin:
-David Johnston lives here (co-founder of BitAngels)
-Open Transactions started here (though it has since moved to Switzerland to get away from US regs)
-First women's crypto organization was started here.
-Texas Bitcoin Association is basically Austin being welcoming
-Texas Bitcoin conference was surprisingly big considering it was a first for our area and started kind of grassroots from Meet-ups
-Meetup scene is pretty lively from generic crypto to crypto dev to Mises and crypto.
-Cointerra is here.
-Texas is one of the few if not the only state to provide clear guidance on crypto and the guidance is very favorable for a crypto business. (basically saying buy and selling your own is not money transmitting. Holding crypto for others is not money transmitting)
