Yes but how many counterparty coins will Ken need to buy to make this work? Also how does Ken issue more shares? Because it's 10,000,000 in the wild until 0.0025 is paid, and then another 15,000,000 enter the wild. So does counterparty allow Ken to issue more shares? Or if not, can he issue all 25,000,000 at once but force a logic rule on the 15,000,000 preventing dividends until the 0.0025 is paid?
Ken would have to issue all 25,000,000 shares up front. He would not be able to use the existing interface to pay dividends until after the 0.0025 is paid however it shouldn't be hard to pull the ownership list and filter out his own addresses when making payments manually.
For example you can see an asset list on their BlockScan site and see who currently holds those assets.
