Today, a Bitcoin miner from the Satoshi Nakamoto era transferred 100 BTC, presumably selling them off after holding them for 16 years—impressive! 16 years ago, these BTC were worth only $7. Now, they're worth $7 million. A million-fold increase! They just sold them a bit too low now. If they had held them for another 3 years, they would be worth at least $20 million, and could have multiplied two or three times over.
