Bernstein analysts predict MicroStrategy will own 4% of the total bitcoin supply by the end of 2033, an amount they expect to be worth about $830 billion.

Short seller Andrew Left of Citron Research revealed on Nov. 21 that his firm had taken a short position in MicroStrategy (NASDAQ:MSTR), the software company that has become a prominent Bitcoin owner.

The architect of the company’s audacious Bitcoin-hoarding strategy explains why he calls the crypto “a flow of money from the 20th century to the 21st century.”
