And that's I think the answer I was looking for, at least. And that's good, I like that answer. As long as you're keeping a solid balance between the BTC-weighting line of the portfolio and publishing the financial reports, I'm going to keep buying shares.
It's fine as an answer IF you look at the investment in isolation rather than as part of a portfolio or larger position.
Where it isn't fine (and actual numbers are needed not vaguaries like "overweight") is in the following scenarios:
1. You want to manage your exposure to various things (X% BTC, Y% silver, Z% LTC etc etc). You can't do that without knowing what percent of exposure the fund will have to BTC.
2. If you want to invest to balance/hedge against another investment that's long on BTC - that's entirely impossible if the majority of assets backing TU shares are actually BTC-denominated themselves (you end up increasng your long position more than you counter it).
3. You have X BTC and want to invest X (or nearly X) in silver - impossible to do.
4. You want to buy options. Totally impossible to do so in an informed way - if the price of a share is .06 now then buying calls at .08 is horribly risky - as usagi may decide the portfolio is "overweight" and issue a dividend totally devaluing the calls you just bought. It's also horribly inefficient as a lot of that price is BTC/equivalent which isn't what you want to buy an option on anyway.
5. You want to buy silver. Rather than paying an $X markup for postage/storage/etc you have to pay a Y*$X (with Y being way greater than 1) markup for capital sufficient to generate profit of $X to cover the postage/storage/etc.
The ONLY people the plan actually works for are those who:
a) Believe in usagi's investment skills (as opposed to just his ability to store silver)
b) Don't specifically want their investment mainly or entirely held in silver
c) Aren't fussed about managing their personal exposure to different currencies/assets to any great extent
d) Either don't want to redeem for physical silver or are happy to end up paying way over the odds (compared to buying it locally in cash with no counter-party risk) when they do so.
Now there IS a problem that has to be addressed one way or another - how to pay for storage fees etc if people just buy the shares and hold them (generating no revenue). Writing covered calls on silver (NOT shares) was the means identified in the original contract - but that's badly flawed for various reasons. What's happening is an attempt to address it by a different way to what most funds use (which is taking the fee from the actual silver) - which is a great objective but this isn't the way to do as the unintended consequence is that teh fund ceases to be a silver fund in any meaningful sense (i.e. the majority of assets backing each share are NOT silver any more).
Here's the easy way of doing it (there's a more complicated option where you sell BTC-denominated bonds so that BTC assets are cancelled out in terms of exchange-rate exposure by matching liabilities):
1. Create one security (a bond in effect) which is pure silver. Shares in it represent silver and are sold at a small markup to spot/cost - designed based on expected split between holders and redeemers so that it has a small positive expectation. Shares in this represent ownership of silver NOT of the asset itself and pay no dividends.
2. Create a second asset which owns the first. Sell shares in it. This one is a pure BTC investment vehicle - it owns the first one, pays the bills and keeps the profit. Provided operation of 1. has a positive expectation then this is better for investors in 2. than NOT owning 1.
This way:
People who want to invest in silver or trade options on it or buy it can do so via 1 in an efficient manner.
Those who believe in usagi's investment skills but don't like silver's prospects can invest in 2.
Those who like the current setup can invest in both.
The markup at which security 1. is sold can then be dynamically adjusted so as to make a small profit for investors in 2.
Tyring to mix these two things in one security is just horrible from the perspective of any investor who wants to be able to invest efficiently in specific assets (e.g. silver) and have control over their exposure to different things.
