We continue Gold for the 21st Century this week with Thomas McMahon, Co-Founder of Abaxx Technologies. David Greely sits down with Thomas to discuss how the role that gold may play in our financial system in the near future is not that different from the one gold and silver played in the not-so-distant past. They also explore precious metals' market evolution in the latter half of the 20th century and its implications for the role of gold in the 21st century.
