A collector claiming to be John Galt on the Bitcoin Talk forum recently successfully redeemed a rare Casascius physical Bitcoin coin, redeeming 100 BTC worth over $10 million. According to its disclosure, the coin was purchased for $500 in 2012, with an investment return of approximately 2000000%. Casascius physical coin was issued by Mike Caldwell in 2011, embedded with a real Bitcoin private key. Due to regulatory reasons in the United States, it was discontinued in 2013 and has now become a high-value collectible. Data shows that over 10000 Casascius physical coins have been redeemed so far, with over 18000 still unused. (Cryptoslate) http://(wublock123.com)/index.php? m=content&c=index&a=show&catid=6&id=44903
