Odaily Planet Daily News Micro Strategy founder Michael Saylor spoke at the Bitcoin Conference, saying that as adoption grows, the price of Bitcoin could exceed $13 million by 2045, which requires an annual return of 29%. At this level, Bitcoin's market value will reach $280 trillion, accounting for 7% of global wealth. He added: "In a bear market, the price of Bitcoin may be $3 million, accounting for 2% of global wealth; but in a bull market, the price of Bitcoin may reach $49 million, accounting for 22% of global wealth." Under Saylor's leadership, MicroStategy has bought 226,331 bitcoins in the past four years, currently worth about $15 billion, about 80% higher than the cumulative purchase price. (Bitcoin Magazine)
