And I have had some Maxcoin (accidentally mined, my fault) in the Auto Exchange Wallet for a day or so.
Not sure if that is normal but all the other coins I have on Auto Exchange usually move to On Exchange pretty quickly.
I've had maxcoin and adzcoin in the auto-exchange for over a week. I think both are dead... the auto switching mined them, at least it a small amount.
Both coins are only traded by MPH at Yobit. Most likely an exchange problem, plus both coins are lower volume than most coins on MPH. I know when I mined MAX it always took longer to exchange than other coins.
