I was tracking coverage of the Wyoming Blockchain Coalition over the past few months (including here) and while it's exciting to see that less taxes will be implemented on crypto, it doesn't stop the Federal government from taxing crypto. The federal level tends to be where heavy taxation is here in the states. In this case, Wyoming is not (to my knowledge) a particularly heavy state tax state to begin with. When I used to live in Texas, there were no income taxes from the state level and almost all withdrawals from paychecks came from the feds. Businesses also had veryyy beneficial tax breaks in Texas. (And with regard to Federal taxes, there is a new federal tax bill being put into place for 2018, but I'm not sure how much of a difference it will make on the whole for crypto. )

Anyway, it's still exciting to see how cryptocurrency is treated by various governments from a tax perspective, and as you stated, maybe crypto companies will migrate their HQ's to Wyoming. (Whether they physically locate there or not is another story -- hilariously enough, Facebook is technically operated out of Delaware because of the beneficial taxes, but its HQ is obviously in the Bay Area here in California. Hah.) Crypto taxation will clearly be an evolving field in the coming years and I'm sure tax lawyers and accountants will have to scramble to keep up!
