MicroStrategy Inc.’s entry into the Nasdaq 100 opens up the largest corporate holder of Bitcoin to a new — and untapped – investor: the index-tracking juggernauts.

Retail investors poured nearly $11 million into MicroStrategy's shares on Monday, almost three times their average daily inflows this year, after the biggest corporate holder of bitcoin secured a spot in the Nasdaq-100 index.

The software company's potential addition to the S&P 500 index could be an even larger opportunity in the medium-term, the report said.
