No the price of the ETF would trade higher then the underlying amount of bitcoin held. As a result the APs would have an incentive to purchase more bitcoin on exchanges, convert the bitcoin to shares of COIN and sell the ETF in the market, causing the spread between BTC and COIN to decrease; this process would be repeated until the spread would not be worth the risk for the AP
3 scenario's
1) as quote above says selling higher to incentivize fun managers ("authorized participants") to buy more baskets
2) price mirrors bitcoin average price/5 because shares are backed by bitcoin no one would pay alot more
3) prices are below once you take into account fee's
i think that share prices will be close to a 5th of a btc (5shares=btc equivelent remember). and fund managers ("authorised participants") dont care* if bitcoin goes to $5000 or $50. because they are getting a set commission per trade.
much like how btc-e, bitstamp, etc dont care as they are making 0.2% for from the buyer and the seller. so these fund managers controlling their basket of 50,000 shares could make alot of money just buy having a basket that kept swapping between clients hands.. without any hard work at all.
for instance.. take bitcoin exchanges.. if btc-e have a trade volume of 10,000 coins a day they make 0.4% per trade (0.2 buyer 0.2 from seller). just by having the 10,000 fly through different peoples hands btc-e makes 40btc profit per day.
the basket managers if their 50,000 shares were to change hands per day, they are making alot of money doing nothing but sitting there watching the screen fill up with transaction fee's. if the fe was 1%, they can simply buy another basket in 100 days without even lifting a finger.
and if the share price sticks to roughly bitcoin price, then the managers get a known daily income. yes we will se spikes that will incentivize managers to buy more coins to add more baskets, which would raise true bitcoins up to mirror the winkledex again
*well they do care because 1% of $5000 is better then 1% of $50.. but thats another level im not above the point im making
