Have you heard about the release of StellarX exchange that supposedly allows the trade of crypto, fiat, commodities, etc.? It seems to be doing one thing I was looking to BTS to do with some upcoming changes I'd heard about, namely allow a trade between altcoins without having to move in and out of BTC/ETH to do it.
I'm still long BTS and intend to be, but the DEX frontier is definitely expanding with some interesting new plays.
(You can see more about StellarX if you care to in this Medium article) from them.)
