Agreed and I misunderstood although (possibly my reading of) your wording seems to indicate a sinister intent.
The company is able to bill the trust for the small management fee (unstated but 0.5% annually is a common amount) and the NAV will decline over time but I wouldn't call it "only they benefit". If there is no benefit to shareholders (of the trust not the management company) then they won't buy it. I mean it is an open market. Investors will weigh the value/utility (if any) of the fund vs the cost (in terms of annual management fee). They buy because the value outweighs the cost.
I would argue there is a lot of potential utility here:
* A company which had a margin brokerage account could accept BTC for goods and hedge volatility between time of acquiring and time of selling by selling short the fund.
* Speculators looking to go long could use margin to extend their leverage at lower cost and risk compared to systems like bitfinex.
* Long term holders of physical BTC (in cold storage) could sell covered calls against the fund for USD cashflow without needing to periodically sell off BTC on exchanges of unknown risk.
* Buying calls and puts would be a more sophisticated way of trading Bitcoins without dealing with entities of unknown trust.
* Someone looking to borrow BTC but sell them for USD could hedge out the currency risk partially or fully through the use of options. If nothing else buying way out of the money calls would be a method of capping currency risk.
