[Bitpush] Bitcoin that has been dormant for ten years suddenly awakened.
Two wallets tied to Casascius physical coins have recently moved—transferring out a total of 2,000 BTC in one go, worth roughly $180 million at current prices. These coins have been sitting since 2011 and 2012, when Bitcoin was only a few dozen dollars; now it's approaching $90,000.
Speaking of Casascius, we have to mention Mike Caldwell from Utah. In 2011, he started this project: embedding private keys into metal coins, sealed with a tamper-evident holographic sticker, with denominations ranging from 1 BTC to 1,000 BTC. You can think of it as a physical version of a cold wallet, but in the form of a commemorative coin.
But the good times didn't last. At the end of 2013, the US Financial Crimes Enforcement Network targeted him, claiming he was operating an unregistered money transmission business. Caldwell had no choice but to stop producing pre-loaded coins. Since then, these physical coins have become rare collectibles.
