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.

Shares in MicroStrategy, the largest corporate holder of bitcoin, initially jumped and then fell Monday after the software company said it had bought $5.4 billion of the cryptocurrency.

MicroStrategy continues to add bitcoin to its balance sheet, buying another $5 billion worth of the token last week.
