Bitcoin reaches its then all-time high near $19,783 on multiple exchanges on December 17, 2017, bringing mainstream attention worldwide. Front page of every newspaper. Your uncle asked you about Bitcoin at Christmas dinner. CBOE Bitcoin futures had launched just days earlier on December 10, and CME futures followed on December 18. The price had risen from under $1,000 in January to nearly $20,000 in twelve months -- a 20x return that defined an era. A brutal two-year bear market would follow.
