What's going on with Mt. Gox?

It's a whole new Bitcoin Builder!

If you have a "goxbtc" balance from before, don't worry, it is still untouched on your account.

As the Japanese trustee and Kraken (see this announcement) work through the bankruptcy proceedings, we will continue to represent the interests of Bitcoin Builder users (and all Mt. Gox depositors) to the best of our ability. If there are any actions we need you to take, we will email you directly, and generally announce them on twitter. We do not expect there to be any.

On April 22, 2015, the trustee posted instructions on how to process a mtgox bankruptcy claim at mtgox.com. Bitcoin Builder filed their claim the same day, and now await official word on the status of the claim (which they have said should be around the next creditor's meeting on May 25th, 2016). As of February 17th, 2016, Bitcoin Builder's claim had not been processed (it was not BTC-only, which they have been processing first).

Bitcoin Builder also filed via Kraken so that if BTC payouts are allowed, they will be able to receive them. At which point users with GOXBTC in their Bitcoin Builder account will have them converted to the final appropriate amount of BTC (which they will then be able to withdraw).

For any funds you have on Bitcoin Builder, no action needs to be taken at this time. (If you had your own mtgox account with any assets in it you should have filed your own personal claim individually.)

Hang in there!

Josh Jones
