Bitcoin isn’t just money. Sometimes it becomes a digital gravestone that no one can ever erase. In 2011, when brilliant cypherpunk Len Sassaman passed away, his friends - including Dan Kaminsky - did something beautiful. They carved a detailed ASCII art portrait of him into the Bitcoin blockchain, with the words: “Len was our friend. A brilliant mind, a kind soul…” All of it permanently etched in block 138,725. A memorial that governments, corporations, or time itself can never delete. Some even whisper he might have been Satoshi. The blockchain quietly holding human stories like this? Straight chills.
