Jon ‘DRJ’ Najarian was linebacker for the Chicago Bears before he turned to another kind of contact sport – trading on the Chicago Board Options Exchange. He became a member of the CBOE, NYSE, CME and CBOT and worked as a floor trader for some 25 years. He built and sold a number of companies, including a $750 million exit to E*TRADE in September 2016. In this conversation, we discuss the physicality of the old school trading pits, how Wall Street has evolved over the years, Robinhood, Davey Day Trader, why Jon and his brother are building a company to educate investors, and how much of his portfolio is currently in Bitcoin. ===============================  The BTSE exchange allows you to trade confidently.
