Thus they were traded in the Digitalis Open Transactions Server for years and nowadays, since Open Transactions never did get to the "ready for your grandmother to be able to use" stage of develpment, we have been migrating them to the HORIZON and STELLAR platforms.
I have been trying to list at http://makemoney.knotwork.com/ the assets thus far migrated to those two platforms, though I suspect there are still some assets that have been implemented on the platforms but that I have not yet gotten around to creating pages for on the Makemoney Knotwork site.
I also continue to update the tables of asset values periodically, see http://galaxies.mygamesonline.org/digitalisassets.html and hey if you can figure out why the "plot" pages do not work and how to make them work that'd be great, they are done using "GNUplot" and worked fine when I generated them using Fedora but have never worked since I switched to using Ubuntu. Somehow GNUplot's generated webpages just show up blank for me (and many others apparently) since I started using the GNUplot that Ubuntu provides.
I usually market-make for I0Coin and IXCoin in units of 100 coins, every 5 satoshis of price on the buy side and every 10 satoshis of price on the sell side. Though at insanely low prices such as IXCoin is at now on the two exchanges where I still trade it I have been trying to go for every satoshi of price on the buy side.
So I guess if you want to buy some I0Coin I can sell you some starting with 100 at the price shown on the above-mentioned price list of Digitalis Open Transactions Server assets and going up 10 bitcoin-satoshis worth of price per each subsequent 100 coins. As the price rises I can probably do deals too; usually all the bitcoin that comes in from folks buying my sell-side offers goes right back onto the buy side.
