@ David Rahaby ... as you say you are long-minded (and I believe you) have you considered just how much the management fees will eat into your BTC over the years? IIRC correctly the annual fee is 2% of NAV and it is taken in BTC not USD, so if you start with 100 BTC ...
After 10 years = 81.7 BTC
After 20 years = 66.8 BTC
After 25 years = 60.3 BTC
[...]
Meh, I'm out of my element here (retirement fund
and in the US), but isn't this a bit of a simplistic comparison?
As I understand it, the relevant point here is that GBTC is compatible with a Roth IRA, which is (intended to be) tax free, so depending on how capital gains for "raw" Bitcoin holdings are (and will be) taxed, and whether you are planning to pay those taxes (or, if not, whether you get away with it), those "2% per year" could either turn out to be a lot, or not that much.
Someone more knowledgeable on the topic, please feel free to correct me if the above is factually wrong.
Hey, I'm open to being corrected to too
But as I see it, this is not a simplistic comparison - simplistic compared to what ? This is one 'predetermined' side of the coin that any 'investor' needs to consider before putting funds in. I am no expert on retirement funds either, but what is crystal clear is that 40% of your BTC will have been paid away in fees if you hold for 25 years. Period. You might as well call it 'tax' (meet the new gubinment - same as the old gubinment
)
The tax implications of holding it for less than x years or trading in and out of, I have no idea about, other than I would assume that holding it for less time will give less tax relief, if any. Just pointing out that if the motivation is solely 'reduced taxes' and holding period is 'until retirement', you are paying a very high 'tax' for the privelege, one that can only be weighed up against individual circumstances. That's the other side of the coin ... ok ... yeah, that side is not so simple
EDIT: If you are unlucky enough to buy at a price that gives you NO capital gains, you will have an extra 40% loss that you would not have incurred otherwise (in the 25 yr scenario)
