I will bid my 1BTC to your 0.5BTC that the US dollar ceases to be an international reserve currency before BTC trades with a daily VWAP under 1 dollar (US2013 PP).
I will bid my 0.5BTC to your 1BTC that the US treasury defaults on debt before BTC trades with a daily VWAP under 1 dollar (US2013 PP).
