I've used MCXNow since late spring...haven't used it in over a month but all was kosher last time I traded some BTC for Doge...never had any issues exchanging LTC for BTC earlier this year either. Sadly, I am unable to recover my Google authenticator and am unable to sign in due to this issue so I won't be doing much trading there unless I create a new account as we all know how friendly RS is when people lose their info etc. Fortunately, I never left a balance overnight on any exchange.
