MicroStrategy (MSTR) will officially join the technology-focused Nasdaq-100 index on December 23, becoming another highlight in the Bitcoin market. As the largest corporate holder of Bitcoin, MSTR's stock has risen nearly 500% since the beginning of the year, attracting the attention of several large ETFs, including the QQQ ETF, and is expected to bring in over $2 billion in purchases. Analysts believe that this move not only enhances MSTR's market position but also paves the way for its potential future inclusion in the S&P 500 index.
