I'm holding out for sure until Winklevoss IPO hits which values coins at $100 each. Lets see if the institutional investors like Bitcoin, easy to purchase a stake in.
If you are going to rely on the S-1 please READ the S-1. The ETF doesn't value coins at anything. To pay the registration fee they need to provide an approximate IPO because the fee is a % of the fund value.
The price they used in the S-1 was the volume weighted average for the price across the three largest exchanges on the day of the filing and for the sole purpose of paying the SEC their fee.
Proposed maximum offering price per Share(1): $20.09
(1) Estimated solely for the purpose of calculating the registration fee pursuant to Rule 457(d) under the Securities Act of 1933. Each Share comprising the initial Baskets of Shares represents 0.20 Bitcoins and is offered at a per Share price equal to the price equal to the number of Bitcoins comprising such Share. The price of Bitcoins is based on a weighted average of the average of the high and low transaction prices of Bitcoins on June 27, 2013 on three major Bitcoin Exchange sites: Mt. Gox K.K., Bitstamp and BTC-e.
If they would have filed the day Bitcoin hit $266 they would have used that price for the filing as well. If/when the ETF is approved, the initial baskets of shares will be sold pre-IPO at the CURRENT price whatever that may be $20 or $20,000.
