Hey mate this coin has been down on the exchange for a little while (along with a few others) due to some system upgrades that were required to increase the stability of the wallets.

At the start of the month we had around 40-50 coins all either disabled or in maintenance mode due to this, we have since brought back online about 30 of these. The remainder we are having various issues with getting the wallets back up and running e,g no explorer, no nodes to sync to or no location to download the code base from.

Greencoin unfortunately was one of these that needed updating but we also had a number of issues getting the new wallet back in sync. The good news however is that it was brought back online yesterday and so far has been running nicely on its new system.
