As we have continued to create Excel models based on Modern Portfolio Theory, we recently added GBTC, a Bitcoin ETF from Grayscale into the investing universe of assets we are considering. On Jan 10, 2024 a new handful of Bitcoin ETF’s came into creation and all of them have lower expense ratios when compared to the Grayscale product at the time of this writing. Currently the annual expense ratios for the available Bitcoin ETF’s are; 0.19% (EZBC), 0.20% (BITB), 0.21% (ARKB), 0.25% (IBIT, HODL, FBTC, BTCW, BTCO) all of which come in under the 1.5% expense ratio on the Grayscale Bitcoin ETF (GBTC).
