Donkey and Ander - saying that "BitUSD is the currency of the future" is not very ambitious. Here's why you're wrong:
1) You're assuming that in the long run people will continue to prefer Fed-controlled fiat currency over the guaranteed scarcity of crypto.
2) As I said before, collateral requirements will make it such that the value of BTS must be far greater than the value of the combined BitAssets issued on top of it. Many aspects of the superDAC, especially the fact that it will support a "currency" token and not just "company shares", requires that the superDAC itself maintains the currency-like properties I have outlined above - (i) fair distribution, (ii) scarcity (non-inflationary), (iii) efficiency (DPOS), and (iv) security.
3) The reason serious investors (governments, institutions, high net-worth individuals, etc.) look for these properties is that they expect currency to be the lowest risk and most stable unit of account. Building currency on top of a protocol layer that does not meet these requirements (or has weaknesses) does nothing to alleviate such concerns.
Personally I believe a couple/handful of cryptocurrencies will rise to global status and that they will gradually replace fiat currencies. BitAssets will play a huge part as (i) a stop-gap measure to onboard new users while crypto is still young and misunderstood and (ii) as an investment vehicle for traders who wish to hedge into non-crypto positions. The superDAC will have incredible features that may be appealing to a lot of people (including myself), but the new Bitshares PTS would have better distribution, strong scarcity, and would be a far better currency and sharedrop instrument. Different models for different applications.
