A Bitcoin whale that had been dormant for over a decade has suddenly awakened.

Two old wallets tied to Casascius physical bitcoins recently moved nearly 2,000 BTC in one go—at current prices, that’s roughly $180 million. These coins had been sitting untouched since 2011 and 2012. Back then, BTC was just a little over $10 each, and now it’s approaching $90,000—a staggering increase.

Casascius was a legendary project in its day, embedding private keys directly into physical coins, making it one of the earliest forms of cold storage. Unfortunately, it stopped production after FinCEN took notice in 2013. Now, with these old coins suddenly on the move, everyone is wondering what’s really happening behind the scenes. Did the original owner recover their keys, or did someone manage to crack something? The market is buzzing with speculation. In any case, this move has reminded many people of that old saying: Bitcoin never sleeps, whales do.
