The SPDR S&P 500 ETF Trust (NYSE: SPY) boasts a remarkable legacy as the largest and most popular exchange-traded fund, with over 630 billion dollars in assets under management. Launched in January 1993, it was also the first ETF to list on U.S. exchanges. However, BlackRock’s recent introduction of a Bitcoin spot ETF is gaining traction, creating buzz in the investment community. As investors weigh their options, the comparison between a seasoned ETF like SPY and the innovative Bitcoin ETF reflects the changing dynamics of the investment landscape, highlighting a shift towards digital assets.
