At the Benzinga Future Of Digital Assets event, Brett Harrison, former president of FTX US, predicted a Bitcoin spot ETF could be approved in 2024. He believes the potential of cryptocurrency has not been fully realized and that the approval of a Bitcoin ETF is not entirely priced into the market. Harrison also speculated on the growth of the derivatives market and the impact of an ETF on spot cryptocurrency volumes, suggesting that authorized participants would need to trade the spot to maintain arbitrage opportunities between the spot market and the ETF.
