Hm, looks like this is a problem with my English. BCNext's idea is that NXTs shouldn't be used as mean of exchange.
Ouch - so we should instead exchange things that are just IOU's in place of something that actually at least has scarcity.
Although maybe Ripple screwed up by trying to make too much out of Ripples I think that unless you have atomic cross-chain transaction support so you can trade something of *real* value (such as BTC or LTC) then this would be a disaster.
