Yeah, I think a lot of the DEC selling is getting into STEEM to buy cards and getting into STEEM to eventually cash out. I don't know what the percentages are. Opening the market to DEC directly will be a big help I think.
If people buy the remaining Orbs at the 100 + 10 promotion rate, that still will cost 341 million DEC. Some are given away as mystery potion rewards, but those cost DEC too. Net-net, there's a whole lot of demand coming to the pipe.
