A Bitcoin collector bought a rare Casascius bar for $500 and now has a profit of over $10,000,000.00.

According to Cryptoslate, a collector who goes by the name John Galt on the Bitcoin Talk forum recently successfully redeemed a solid gold Casascius physical Bitcoin bar purchased in 2012, extracting 100 $BTC from it, currently worth over $10,000,000. It is reported that the gold bar was purchased for only $500 at the time, with a ROI of approximately 2,000,000%. Casascius physical Bitcoins were issued by Mike Caldwell in 2011 and embedded with real Bitcoin private keys. Production was discontinued in 2013 due to regulatory pressure, and they have now become rare collectibles in crypto history. According to casasciustracker.com data, over 10,000 Casascius coins have been redeemed, with over 18,000 still unused. [ChainCatcher]
