Feb 5 (Reuters) - MicroStrategy ( MSTR ), the biggest

corporate holder of bitcoin, said on Wednesday it would

now operate as "Strategy" and unveiled a new logo to emphasize

its commitment to the cryptocurrency space.

The rebrand was "a natural evolution" as it seeks to

integrate bitcoin - the world's biggest and best-known

cryptocurrency - into the heart of its business operations, the

company said.

MicroStrategy ( MSTR ), founded by Michael Saylor, has emerged as one

of the biggest beneficiaries of the soaring popularity of

bitcoin. Its shares jumped nearly five-fold last year, helping

it secure a spot in the Nasdaq 100 index in December.

The company continues to be an aggressive investor in

bitcoin. In the statement announcing its rebrand, MicroStrategy ( MSTR )

defined itself as the world's "first and largest Bitcoin

Treasury Company".

Its new logo includes a stylized "B" that signifies its

bitcoin strategy, it said.

The company is scheduled to report its quarterly earnings

later on Wednesday.
