General Discussion / Re: BitUSD across DACs
« on: October 23, 2014, 01:24:06 pm »you cannot move bitUSD from one DAC INTO another DAC ... you can trade 1:1 between DACs ..
the amount of bitUSD in BTSX will always be completely backed by BTSX .. same holds for any other chain ..
you can think of a second market maker .. that trades bitUSD back an forth between chains .. while achieving a few percent profit ... inter DAC bitUSD trades might not be 1:1 .. because they require additional complexity/work ..
have you ever transfered money internationally?! same thing!
But you can't trade 1:1 between DACs, and there is potential for a significant spread. If BitsharesX becomes wildly successful and Peertracks doesn't gain traction, then the large difference in volume on the internal exchanges of each chain could produce spreads in excess of 10%.
So imagine you are a new user of both Bitshares and Peertracks and this difference has not been clearly expressed or stated. Lets also assume there are easy to use gateways into each chain via credit card as well as a "transfer BitUSD" feature built into each application that executes BitUSD trades between chains for you on the backend at the current market rate.
You "deposit" $100 from your credit card into Peertracks, and in return you receive 100 BitUSD (but for all intents and purposes this is PeertracksUSD). You buy some music then decide that you want to "transfer" the remaining BitUSD over to your Bitshares account. After completing the "transfer" you notice that you were charged a "fee" (which is really just the spread between the PeertracksUSD and BitsharesUSD). Even if the spread is 5%, you've just significantly soured the relationship with and completely confused the user.
