They wouldn't of added it to the market and announced adding it on twitter if it wasn't ready. I guess there's thousands of deposits/withdrawals going on and it takes time to process them.
This "delay" happens too when they put up mint,dark and cach earlier, they said "Trade engine for these markets are offline until the morning to allow our wallets/security to catch up and prevent many deposit issues that arise soon after coins are listed"

Thanks for the info, I guess we're going to be in for an interesting morning. Hope the BTC sell off stops as it seems to be dragging the entire crypto world with it. Nice to see SMC isn't affect I guess the low volume came at the perfect time. SMC is basically immuned to sell off at the moment due to extremely low volume.
