Dargo, regarding the recent BTC/ETH switch to ETH/BTC. I believe if you would do the same for LTC to make it LTC/BTC it would help with the volume on that pair. I would consider that as a good step. You can always check people who traded LTC in last months and send them a poll. I think they will be happy about the switch, and you should be happy about higher volume.
Cheers
MusX - thanks for the suggestion. We are considering this. To make the change directly (as opposed to adding a 1/x layer), we'd have to cancel all open orders on the BTC/LTC pair and let people create new orders on LTC/BTC. We wouldn't do it without adequate warning of course. How do you think people would feel about their orders getting cancelled? My sense is that people would probably welcome the change and wouldn't mind the inconvenience of order cancellation.
