I understand and like 'free floating' asset prices, 'pegged' screams of manipulation of price. So what's the purpose of those, can anyone give a use case?
The peg is still market determined. The difference is while anyone on NXT can create an Asset called NXTUSD.
For that to track the value of an actual dollar, it would either have to be backed by the issuer which is centralisation and nothing special at all kind of like Realcoin. Otherwise there's absolutely no reason anyone would value it at close to a dollar.
However BitAssets are covered by BTSX as collateral, so participants can agree to trade around the value of anything, Bitstocks, BitCurrency, BitCommodities etc. knowing the position is covered.
This video is a bit dated (They call it BitShares in the video when it's actually BitShares X now.)

The OpportunityGiven the current global financial instability, geopolitical tensions & high levels of government debt, holding sizeable deposits of fiat, stocks or commodities is becoming increasingly risky within the current financial system. Therefore, BitShares X may need very little real-world proving under its belt, before it is seen by some very big players as an appealing hedge for a portion of their portfolio.
Indeed should those centralised risk factors get worse or even materialise - such as significant deposit confiscations - BitShares X will be in a dominant position to displace a large part of a multi-trillion dollar industry virtually overnight.
Target Markets TradersIt should go without saying that the privacy, low costs, freedom from confiscation and other advantages of trading on a blockchain will appeal to many of the hundreds of thousands of traders currently engaged in trading currencies, commodities and stocks all around the world.
In order to support such trading activities, BitShares X introduces TITAN - A brand new privacy feature which allows for fully secure, anonymous transactions, transferred to and from easy to remember user-created, account names.
Bitcoin Retailers and UsersThere are over 30K+ retailers who currently accept Bitcoin as payment; however the vast majority, due to tight retail margins and the relatively high volatility of Bitcoin, transition directly back to fiat via a third party service like BitPay. Many of these retailers may wish to hold a portion of their revenue in Bit-Assets such as BitUSD.
Similarly the thousands of Bitcoin and alt-coin holders may also wish to hold a portion of their fiat earnings or savings in less volatile assets such as BitUSD, BitCNY or BitGold.
Existing Hotspots Places like Ukraine, Venezuela, Argentina, Ghana and many Asian countries have significant capital controls that already restrict the flow of capital and foreign currency. The need for BitShares X to fill a void caused by these restrictions is clear, so it makes sense that there may be rapid adoption in areas like this, as they were also some of the strongest areas of initial Bitcoin adoption.
