What does tracking Bitcoin mean?
A spot Bitcoin ETF holds Bitcoin through a custodian. The issuer divides assets minus liabilities by shares to get net asset value per share, or NAV. Authorized participants, usually large broker-dealers, create and redeem large blocks of shares in exchange for Bitcoin. That arbitrage usually keeps the market price near NAV, and ordinary investors do not create or redeem those blocks.
How to check tracking step by step
The market price can trade above or below NAV, a premium or a discount. Fund fees and cash flows can make the fund's value drift from Bitcoin's spot price. Bitcoin trades around the clock, but ETF shares trade only during US stock market hours.
- 1Find the daily NAVGo to the issuer's site. The NAV page appears once each trading day after the close.
- 2Check the reported holdingsSee how much Bitcoin the fund reports holding. Divide it by shares outstanding.
- 3Compare price with NAVSubtract NAV from the share price. A positive result is a premium, a negative one a discount.
- 4Note the hours gapCompare the opening share price with Bitcoin's overnight move.
- 5Review fees and flowsFund expenses and cash flows can make NAV drift from Bitcoin's spot price.
After buying: records and account safety
Keep your trade confirmations and cost basis records. ETF investors usually owe capital gains taxes only when they sell shares at a profit.
