New York's heavy-handed Bitcoin business regulation (the "BitLicense") has caused at least one player to abandon the New York market: https://www.bitfinex.com/pages/announcements/?id=51.

Bitfinex's move comes following outcry when the new regulations were first announced. Businesses complained that they'd be forced to leave New York due to high compliance costs and it seems they were right. That said, Bitfinex is a Hong Kong-managed British Virgin Islands company so this isn't a case of a domestic company being forced to leave.

It appears that Bitfinex will still offer some limited services to New York residents but not its exchange features.
