MicroStrategy rebranded on February 5, and it's called Strategy, with the “₿” Bitcoin logo next to its name.
Michael Saylor founded MicroStrategy in November 1989, and the company had never rebranded before.
This move is likely decided to further signal the company's devoted focus on Bitcoin.
The company is now a de-facto Bitcoin, and one of the largest individual holders of BTC in the world.
At the time of writing, Strategy holds 471,107 BTC at the time of writing.
