I don't think that is possible to trade on Steem-Engine anymore.

The trade page simply gives a message saying "error retreiving market value"

I also think that it is no longer possible to claim rewards.

My guess is that Steem-Engine is not coming back.

There are several coins on Hive Engine that no longer dispense rewards.

My biggest fear is that Steem-Engine shows the future of #hive-engine.
