The topic of cryptocurrencies, and bitcoin more specifically, tends to stir up diverse opinions. Some feel that the emergence of these currencies with no central control and no respect for national boundaries poses a real threat to the security of nations, while others feel that bitcoin represents the future of global banking.

Recently, Brainstorm hosted a roundtable to discuss the impact of this phenomenon and while participants were generally bullish about the future of bitcoin as a currency, opinion was divided over whether the currency itself or its underlying blockchain technology would have a greater impact in the long term.
