Cryptsy historical hot wallet balance

[fairglu]

Based on taint analysis, here is a chart showing the historical balance of Cryptsy's hot wallet.

This summarizes, by day, the deposits, withdrawals and balance of more than 390,000 addresses that could be tied to Cryptsy's hot wallet (raw data: http://pastebin.com/hMpuzHbt).
Note that the taint analysis is still being refined at the moment, more addresses will likely be found.

Interestingly enough it matches the info from the Cryptsy public announcement which has now been made.

Is this data supposed to indicate that maybe Big Vern is lying about it having been a cold wallet that was stolen from, that in fact it was a hot wallet?

(Assuming of course the entire claim of having been stolen from is not a total fabrication itself.)

Addresses can be linked by taint if they are spent together (ie. proof whoever spent them had access to both private keys).

A cold wallet can get tainted if its private keys are "imported" in a hot wallet (ie. at that point the cold wallet becomes "hot"), rather than the cold wallet funds being spent in a transaction to a hot wallet address (which is a probably "cleaner" way to do it, this way cold and hot wallets are kept completely distinct).

It is possible they sent funds to a distinct address (paper wallet), then later imported them, which would have tainted the paper wallet, but the irregularity in the balance seems to indicate they did not have complete, automated hot/cold wallet management. FWIW bitfinex does it, and their hot wallet balance is much more flat and boring, with just the occasional spikes.
