I just notied this too the other day - nice to know they are looking out for us. I am so much happier trading there - I used to be on polo but it just became too much. Sometimes there is not enough volume on some of the coins on Bittrex but that is another issue - the main coins exchange well on Bittrex. Thank you the update i will follow you to keep an eye on further developments.
RE: Bittrex adds excellent default Security feature, should be mandatory on all Exchanges
