We'll
ignore currency issues (including the jurisdiction of the CFTC over such things) for the moment, except insofar as New York's definition of virtual
currency (which you need a license to
move around) is very broadly construed and includes most «digital units of exchange» which could certainly include tokens.
Even if the U.S. dollars falls you should be protected if the foreign
currency moves upward with the Canadian dollar as you mention in this post: «You can essentially
ignore the CAD - USD fluctuation for broad international ETFs like Vanguard Europe Pacific ETF (VEA), iShares MSCI EAFE ETF (EFA), Vanguard Emerging Markets ETF (VWO), iShares MSCI Emerging Markets ETF (EEM) etc., country - specific ETFs like iShares MSCI Japan ETF (EWJ), iShares MSCI Australia ETF (EWA) etc. and even ADRs that trade in US exchanges but are denominated in local
currencies like Nokia (NOK)».
