Glad you like it!
Currently talking with /r/memeeconomy mods to be featured.
Concerning raising number of shares, we are discussing in the democracy section if this should be done and how since it might destroy rarity of some sought memes.
It's realtime, got around 10.000 transactions already, can hold 400+ concurrent connections and got API for bots!
All the economic decisions are made using a liquid democracy (which is almost functional)
Also, how do you create more shares of a stock? I made a sample meme at 10 shares, and realized I wanted to increase the number of shares.
