Guess that is one way to leave some dominate exchanges in the US. It seems the Gov. & IRS don't want outside exchanges. Same applies to many coins unless you are a registered investor. Wonder if this contravenes WTO rules.
I am diligently analysing DEXes*, vezpit; and I know Laser is also paying attention to DEXes. My thought is: those who can must go hard at Nova, to put volume on the 42-BTC and 42-ETH pairs. (Don't like our chances much on the other pairs.)
Then we need to get a DEX listing, which will help our U.S.-based community members -- https://chainz.cryptoid.info/42/# (Go to 'network'; then 'geo-location.')
And in the middle of all this, we gotta trial and find use for our android wallet.
Don't forget: a buy-sell split of 3.6-3.8 is over five percent, which is just fine. If you are trading, why not go for lots of little trades? It all adds up.
