Damn, i was really hoping this was a cryptsy wallet but if you look at the address it has to be an hot wallet for some exchange or company right? LXA3i9eEAVDbgDqkThCa4D6BUJ3SEULkEr
Look at the ammount of volume and funds, anyone have any clue who's address this might be? This would help me out massively, whomever helps me catch this guy will be rewarded!
Cryptsy would never sign that many transactions with one key. Its bad practice. Of course if its a users deposit address there isnt much they can do besides force a new address on them
For that kind of volume I would look at Bitfinex, OKCoin or btc38
