i honestly don't know how much longer that model will hold up. you've got american FINCEN closing in on one side and the EU commission on the other.
I give it a year or two, maybe less, before they either shut down, require KYC from U.S. citizens, or drop support for the U.S. altogether. Can't say what will happen to their ability to provide service to the EU but these are the kinds of regulations we're going to see more of in my opinion.
I am a fan of instant exchanges but haven't used this fox.exchange one and probably wont. My trading days are over anyway, but I hope gov't regulations dont effectively destroy all of them since they're so much easier to use than standard exchanges. Faster anyway.
At the end of the day, shapeshift have basically lost out on a lot of customers because of the direction it took (probably forcibly, it seems) in regards to forcing people to get accounts and verify themselves.
They had no choice as far as the U.S. was concerned so I can't fault them for that. Any exchange that wants to conduct legal business has to comply with regulators, so if they say the exchanges have to go thru the KYC process with customers they have to do it. There's only going to be more of this in the future, not less.
