Bytemaster Dan there is an opportunity here much like how Xeldal outlined to make "calls" "puts" and "borrowing for shorting." 2 types of assets. If you made calls and puts it would dramatically increase the supply of BTS as you are using leverage.
The unstable game of leverage is what we may have to play.
Think about how you can incorporate "calls" "puts" not just "borrowing" and "lending" so that it increases usability. You may be able to find the term to use as you want it contractless contracts which as you have been pragmatic, you may have to give up.
IMHO I dont believe Bonds will fair as well as Stocks when you get there. We just need the feeds and when I mean feeds I do not mean delegates which we will need as well but I mean the reflection of the asset in the market being pegged as bitsapphire outlined in another post.
Also make unofficial assets but that have to be authorized by 51 delegates (ofcourse) (I dont know if this is up right now) but it would be very good and dramatically increase BTS, it just matters that accountability of those assets and would dramatically increase the scope of Bitshares.
