Conclusion: ______
1) either AK is a very large investor with that many coins
2) AK has access to cold wallet
3) DMF deposited all the coins to AK to "frame"
4) AK = DMF
any other possibilities?
I think AK said that:
5) he had lots of coins in his ninja balance, not invested (which explains why we didn't see the site's total invested drop as he withdrew). Also, since those coins didn't show up anywhere public on the site, they didn't need to be taken into account for the "proof of solvency" stuff. That means the site could already have been operating a fractional reserve. AK taking out his coins meant they had pretty much none left.
I think AK said he had only 50 coins on the site which he withdrew but before it was processed the site shutdown. Also based on messages I have exchanged with AK before he said he has never had more than 50 BTC balance on a site before.
