The American Securities Enforcement Agency (SEC) gave the green light for the marketing, the next day, of eleven Bitcoin ETFs. Of these eleven ETFs, ten are based on the spot price of bitcoin (Spot), and one based on futures contracts (Futures). Also, the marketing of Bitcoin Spot ETFs has been launched, with funds that now actually hold bitcoin in their wallets. Of the 10 Bitcoin Spot ETFs marketed, the podium in terms of assets under management consists of the Grayscale Bitcoin Trust ETF (GBTC) in first position, followed by BlackRock's iShares Bitcoin Trust (IBIT), and the Fidelity Advantage Bitcoin ETF (FBTC). The three ETFs have $34.09 billion in assets for a total of $37.65 billion
