ChainCatcher reports, according to Cryptoslate, a collector who calls himself John Galt on the Bitcoin Talk forum recently successfully redeemed a solid gold Casascius physical Bit coin bar purchased in 2012, extracting 100 BTC, currently worth over $10 million. It is reported that the gold bar was purchased for only $500 at the time, with an investment return rate of approximately 2,000,000%.
Casascius physical Bit coins were issued by Mike Caldwell in 2011, embedded with real Bit coin private keys, and discontinued in 2013 due to regulatory pressure, now a rare collectible in crypto history. According to casasciustracker.com data, over 10,000 Casascius coins have been redeemed, with more than 18,000 still unused.
