The statement is factually true and strongly corroborated by multiple credible sources. Evidence from Forbes, Bitcoin Magazine, and Cointelegraph directly states that former PayPal President David Marcus is highlighting Bitcoin's potential as a global payment network. His identity as the former president of PayPal is confirmed by Wikipedia and his own X (formerly Twitter) profile, where he also states he is building on Bitcoin via his company, Lightspark. The claims are consistent across several reliable outlets.
