Building Bitcoin To Last For Centuries

The Great Pyramid of Egypt kept the record for the tallest man-made structure for at least 3,800 years, and its 2.3 million blocks weigh 6 million tons. The huge granite blocks that form chambers in its core weigh up to 80 tons each and are located more than 40 meters above ground level. It’s at least 4,500 years old, and even that barely conceivable age is based on surprisingly scant evidence: there’s a realistic chance it’s significantly older (do your own research, Bitcoiner, don’t trust, check).
