LoL, I'm not sure Pocket will become much, but I would expect Pocket to eventually trade on the exchanges. I would peg it's initial market cap somewhere between 3 to 10 mil. There are plenty of worse things trading above 3 mil on exchanges, so using comparative analysis, it's worth that just based on the method of launch and the novelty.

If other people want to give it a future by making things for it, could rise in value.
