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.

Bernstein analyst Gautam Chhugani, who boosted his price target on MicroStrategy by $310 to $600 a share in a note published Monday, sees the group as a principal beneficiary. Chhugani estimates MicroStrategy owns around 1.7% of global bitcoin and says could grow to 4% over the next decade in his base-case scenario.
