Grayscale has filed for SEC approval to launch the Grayscale Bitcoin Mini Trust, which will be funded by a portion of GBTC shares and offer lower fees than the existing product. Moving from GBTC to the new trust will not trigger a capital gains tax event. The fees for the new trust have not been disclosed but are expected to be competitive with low-cost bitcoin ETFs on the market. Grayscale's GBTC has stood out from rival offerings due to its relatively high fees, but the new trust could appeal to registered investment advisors and broker networks looking for cheaper alternatives.
