About BTC
Grayscale Bitcoin Mini Trust (BTC) is a spot Bitcoin ETF issued by Grayscale. Each share represents a fractional amount of Bitcoin held in trust, with the BTC-per-share ratio decreasing daily due to management fees.
The BTC Equivalent column shows what each day's closing price implies for Bitcoin's value, calculated as close ÷ btcPerShare. This is our key metric — it reveals whether the ETF trades at a premium or discount to Bitcoin.
