Gold has been used for 5,000 years, proving that it is the king of agricultural and industrial civilizations. But we are entering the digital civilization. Holding onto old maps, we cannot find the new continent. BTC doesn't need to live 5,000 years to prove itself; it only needs to survive until the generation that believes in gold has grown old. As for consensus, perhaps there's no need to persuade the old; just outlive them.
