Recording to the IPO results, the coin worth about 0.000002 BTC.
For me, to mine it at the current difficulty it should be worth about 0.001 BTC (500 times fold!).
What has changed?

it's ridiculous!
That was just a pre-launch value based on the total amount invested during the IPO. You're right, the coins should be worth much more (and hopefully they will be!)
