Former PayPal President David Marcus: He believes Bitcoin is significantly undervalued compared to gold. If its market cap matches gold, it would reach $1.3 million per coin, and he emphasized that its payment utility has not yet been factored into the price. Marcus's prediction is based on Bitcoin's long-term potential as the 'Internet of money.' Compared to gold's market cap of approximately $15 trillion, Bitcoin's current market cap of about $1.7 trillion still has 7-8x growth potential.
