At one point there was also supposed to be both BitAsset 1.0 and BitAsset3.0 on the this chain. I completely forgot about that. That obviously didn't happen. There was some complication somewhere i guess, maybe with paying interest.
You are referring to a time long before this even.
It would be interesting to see. I remember that the biggest issues back then were bugs and broken clients. So the market never really had a chance to prove itself.
I'm not a big fan of the current BTA2.0(3.0) implementation for a few superficial reasons like the price not centering around 1:1 parity, and the settlement feature as another detriment to shorts. But I also think it has had little time to develop and there are some ideas about cosmetic fixes like adjusting the feed price by the market premium for that Asset so it trades closer to 1:1 . Starspirit was pursuing a lot of these ideas like couponUSD that would be used with merchants etc, that I don't really fully understand. They were never really fleshed out completely as far as I know.
I'd like to see the current system develop but I agree that the older approach has merit and a certain appeal.
I'm certainly not qualified to come up with something new, but an option would be to use the new private MPA's and just disable the things you don't want, to make it function like the older models.
Is there issue with having various approaches to this? Multiple smartcoins for the same thing with different mechanics. A bitCNY1.0 bitCNY2.0 bitCNY3.0 etc.?
