Grayscale reported on 29 October that its Mini Bitcoin and Ether ETFs attracted $750 million in the first three months, with the Grayscale Bitcoin Mini-Trust and Grayscale Mini Ether Trust spun off from the BTC and ETH funds, respectively, which were listed in July. The mini trust has a management fee of 0.15 per cent, excluding promotional fees, the lowest base fee charged in a spot cryptocurrency ETF. John Hoffman, managing director and head of distribution and partnerships at Grayscale, said in a statement, ‘The success of BTC and ETH to date symbolises the strong customer demand for low-cost crypto ETPs.’
