Bittrex is a cryptocurrency exchange that allows users to exchange Bitcoin and Litecoin for a wide variety of altcoins. We have received an anonymous tip from a trusted source of a leaked chat conversation allegedly from one of exchange's founding members.

Bittrex richie is presumably Richie Lai, who according to Bittrex's website is one of the exchange's founders and works on Amazon's security.

Exchanges often control user funds in a giant pot similar to how a bank functions. So the movement of funds in this matter isn't out of the ordinary, but messing up on this scale will leave the exchange with less money than its customers have put into it. Earlier in the chat, bittrex-richie says this was the first time it happened, although the same user claims to have gotten more double spends credited to his account since.

This reporter spoke to bittrex-richie on the Bittrex IRC chatroom. He assured us that the funds in Bittrex are safe and secure. He says that the problem was caused when a transaction too large issue caused him to have to manually fix the transaction and then accidentally sent the additional funds to the user. He went on to say that the original poster's claims that it happened to again to the same user is false. The transaction too large issue has to do with the BTC protocol, but Coin Control is designed to fix just that. We were told that Bittrex does not use Coin Control and it has only had to manually fix the transaction a few dozen times since the start of Bittrex.
