A notice (link) posted on Mt. Gox’s website, says customers can make bankruptcy claims by signing with their account at claims.mtgox.com. There is also an offline option. Those filing must sign up to, or already have, a Kraken account since any returned coins will be deposited via the service. Returns will be calculated at a rate of $483 per BTC with an additional 6 percent per annum. Mt. Gox customers have until May 29 to file their claim. The company’s creditors plan to make a decision on returns by September 9, 2015.
