The coin flow graph is terrific: http://wizsec.jp/images/theft_flow.svg Is this type of visualization common in Bitcoin? Is it a tool anyone can easily use? Edit , let me restate my question. "Is there a tool that generates Sankey diagrams from blockchain data that is easy to use?"

These are called Sankey diagrams.

Can't wait to get my refund :) It's still insane to me that MtGox never moved coins to a wallet or acknowledged the breach until long after it was too late. You would think if you have billions of dollars sitting somewhere and you realize someone is starting to take them you would, you know, do something .

>Can't wait to get my refund :)

I had like 0.000001 BTC in mtgox and it was worth it for the cute sticky unfoldy postcard thing I got from the Japanese court.

Actually more specific is 'alluvial diagram' [1] since the style emphasizes a 'flow' character.

Same here, I saved mine to show to my kids some day. "Hey look kids, your dad was summoned to a Japanese district court over the loss of 0.0001 bitcoin!"

So according to the following, Vinnik was aware of the origin of bitcoins that were sold on BTC-e: > Some of the funds moved to BTC-e seem to have moved straight to internal storage rather than customer deposit addresses, hinting at a relationship between Vinnik and BTC-e. and he was stupid enough to deposit them back to his account on MtGox: > Moving coins back onto MtGox was what let us identify Vinnik, as the MtGo…

>All in all, there a strong suggestion that he participated in money laundering and was involved in the whole scheme. Well duh, anyone involved in the Bitcoin community was very well aware of this. BTC-e has been flagrantly disregarding AML and KYC laws for it's entire existence.

Lots of people in Bitcoin hate KYC and AML laws, and consider them invasive. I am one of these people.

In itself, it's not an indicator of wrongdoing.

There's no chance of that, right? (Hence ":)")

At the time of the MtGox implosion I was bummed to have lost a few hundred $ worth of BTC. Now I'd be very interested in recovering that balance ... in BTC.

Except potentially breaking the law.
