Thank you. That's informative. Perhaps it's the Japanese government who is facilitating this theft for the benefit of its citizens. If so, they are killing a golden goose.
maybe their capital controls are different then other countries
That's not it. It's obvious U.S. banks are reluctant to deal with Gox, but there's probably more to the story. I think it's likely that the Feds in the U.S. are leaning on Mark to reveal his entire customer database so that they can systematically track down every silk road customer and merchant with a digital paper trail. Every MtGox customer who used the silk road without tumbling their funds through a bitcoin mixer are possibly going to get tracked down. The Feds want to seize the MtGox funds of Silk Road users, but until they know for sure who they are, they are preventing any U.S. withdrawals of fiat. They probably want to freeze the whole exchange to catch these people, but the Japanese government won't let them for national sovereignty reasons. So the Feds stop at the farthest point they can control, the wire xfers to U.S. Banks.
Just a theory.
