Eventually, they too will run out of shares and it will move to 4 etc, etc, etc. At this point it is difficult to believe there are many gaps left to be filled down here so movement should become more fluid once inventory of .0003s had been exhausted. By my count, there are only about 2 billion right now and we move almost that much in a day most of the time. I think 500M a tick or less will be common in the near future.
