BitcoinCharlie: They removed it from all markets.

King56: It's coincidental timing for sure, but I doubt this was due in any way to our new UNO whale. Apparently Bittrex even had a survey where people voted for the distribution feature to remain (I didn't see that survey though).

It's definitely a shame, at least CryptoID is still able to track the Bittrex wallet (albeit mislabelled), otherwise we'd be flying blind.

Maybe down the road they'll reintroduce an even better distribution visualizer, or maybe if they get enough complaint emails they'll put it back. I remember asking Cryptsy to add a distribution feature, a mod likened it to a bank putting all their money in the window. As discussed here, that's not a fair comparison since we could already see their balances for various coins in block explorers. His rebuke was that maybe the wallet totals weren't accurate and they had more than they wanted people to know about, but I'm sure that wasn't the case with Cryptsy at that time, since they had just abandoned normal hot wallets and put the whole Cryptsy balance in one address. The point is, I doubt Bittrex engineers are as dumb as the aforementioned Cryptsy mod, but maybe they see harm in revealing the size of their largest accounts. Showing that a single user has $1,000,000 in LTC just as an example, could aid hackers in determining who specifically to target or what approaches to take in targeting users of certain coins.
