From website:
"Market Closing
Due to being unable to provide any kind of realistic or accurate ETA on both the DOGE/LTC markets being resumed, we have decided it best to close these base markets at this time. Please close any open orders, and we apologize for the inconvenience."
They got soo.. many coins that just one could be a bad-actor and crash it (wallet software) Otherwise a needed site for new coins.
Would take a army of workers to maintain! Mostly with hard-forks etc.
I stopped trading there after my account was almost hacked, maybe was the VPN who knows..
But lost zero.
I hope everything gets sorted out in a timely fashion.
