How do you explain the timing? The withdrawal problems started around the 5th of June. The first Dwolla seizure happened on June 14th. You have nine days to explain.
Gox admits in their answer to Coinlab that money sent to Coinlab's bank accounts was credited to the balances of Gox customers, but the money was actually held by Coinlab. It seems pretty obvious to me that Gox has been facing financial challenges for a while, and when the two major holes caused by DHL and Dwolla converged with a declining volume at the beginning of June, the shit hit the fan.
CoinLab doesn't explain it at all. They had millions on USD in profit, a fat order book and more than 5 million USD on the two bank accounts seized by the DHS.
Finally, 5th to 14th June seems pretty close to me. Maybe the DHL action started a few days before it actually hits the news. Anyhow, it looks obvious to me there are diverse factors that are putting Gox under financial stress.
Dwolla were processing withdrawals until Friday 14th. Only bank wires were delayed. Five weeks for SEPA and more than a week for international wires. If the DHS action started earlier, it had no effect on Dwolla withdrawals which it was supposed to target, but on SEPA (delayed for as long as I can remember) and wires from their bank in Japan. Unlikely. DHS didn't even target MtGox. Only Mutum Sigillum LLC.
Nope. Your explanation doens't work.
