Coinsmarkets is a crap exchange
I though adding BTX, BTDX and BSD to Coinsmarket was a strange move. It is IMO like a starter exchange, I wonder if this has anything to do with the price movement - or does anyone have any theories as to why the price has been underperforming?
I suppose that Coinsmarket decided to list those coins all by themselves.
As of why the price is dropping for BTDX i think it is all because there is no community and no active dev. So the price is actually still quite high imho.
Untill we see some activity around BTDX the price will keep falling.
