Is it right to add this
Decoin to the list, since I think he's pure POS. Trading is already started in his own exchange, have not so much volume because it's in newcomer exchange, but it have the lowest price limit, so can't sell or buy at a certain price.
Its not convincing yet. Because it may have already its independent exchange. But their 24hr volume yet was very low, so many users are still not into it. And it may be prone to be delist at any time, if conditions not met on trading volume.
