Out of the ten bitcoin ETFs, WisdomTree’s BTCW has attracted the lowest amount of assets under management (AUM), roughly $12.8 million (296 bitcoin), according to Bloomberg Intelligence data. Asset management giant Franklin Templeton has the second lowest AUM with $64.5 million. Leading the way in asset gathering are BlackRock (more than $3B AUM) and Fidelity ($2.7B AUM). Grayscale, who converted its Grayscale Bitcoin Fund (GBTC) into an ETF and therefore came into the race with $30 billion in AUM, has bled about $10 billion of that since ETF trading began on Jan. 11.
