For several years, MicroStrategy has established itself as a leading figure in the institutional adoption of Bitcoin, accumulating over 450,000 BTC in its reserves.

The company could potentially owe taxes on its unrealized gains, estimated at $19.3 billion. This unprecedented development in the crypto field raises critical questions about the implications of these rules for companies exposed to these assets and the future of investment strategies.
