Well, looks like this is the result of yet more Gox incompetence. Is it time yet to get out of that exchange yet? How many more of these incidents are Gox users willing to endure?
Well, how to kill US based bitcoin businesses 1-2-3:
1. Issue guidance (Fincen) that they need to have money transmitting licenses.
2. Attack existing companies in the bitcoin industry without giving them a chance to get a license first.
3. Profit
A more fair way to go about things, which should be done by sensible humans would be to say: Hey, you've got a business running, are you aware of the new requirements for licensing ? You have 6 months to comply with the licensing requirements and get a license, or you will have to close up shop.
But in reality it's all about power. Power for the ones sitting on the top of the food chain, and their friends. If they don't like you, there's essentially nothing you can do - there's always something to frame you on.
No one should have to hold their hand, it is their responsibility to ensure that their business meets regulatory requirements, and every other major exchange in the states seems to have figured it out, even before the FinCEN document. I would not feel safe keeping money or BTC in Gox right now, who knows what other requirements they may have failed to meet on the Japan side of things.
