I think their wallet is still in maint mode, so, no deposits atm.
I contacted Cryptsy about the wallet maintenance. They said they do periodic maintenance of all coin wallets. SBC has been trading on Cryptsy for sometime with Buys and Sells. It has dropped in price recently.
There are campers that buy coins at a price they won't deviate from, then sell on short term price increases. This seems to be keeping the price down. Also, there is not much volume. Unless there is some renewed interest in SBC like what occurred in December of 2013, SBC will remain on a slow decline in price.
