Since the same technology is behind each one of these DAC's it will probably make more sense just to switch on trading for all the other currencies in the DAC that gains the widest adoption. No need to trade between chains. Just have the delegates publish the appropriate feeds and away you go. BTSX might be worthless.
No BTSX wouldn't be worthless if it bootstrapped BitAssets and particularly BitUSD first.
Luckily BTSX is way ahead, it has the best dev talent, DPOS & an awesome marketing in the pipeline. So it was very hard to see anything challenging it.
Until now...
VOTE will fork BitUSD, VOTE has DPOS and the best dev talent in the business (Bytemaster), they will apparently be using everything in the BTSX amazing secret marketing campaign too. (Offering BitUSD on debit card
https://bitsharestalk.org/index.php?topic=10118.msg132066#msg132066 except VOTE has dilution so can offer big incentives to customers.) With whatever the secret sauce of VOTE is and BM saying it could be bigger, it seems they could easily bootstrap BitUSD first (including the brand name 'BitUSD') and I struggle to see them not adding BitAssets if they have the main market.
So while not all is revealed to me it currently seems BitsharesX is now in a position where it needs to add dilution so that we can compete with BitSharesY if it wants to bootstrap BitUSD.
