I'm betting on a worldwide market collapse.
Everything we do each day depends on the markets to provide the tempo of our world.
The organization of our daily life depends mostly on currencies and commodities but also on the infinity of others financial products that are all somehow connected together .
The financial system is the biggest machine we ever build and it's enormously complex, chaotic and ultra fast .
With a background of diffuse economic weaknesses all it could take is an unpredictable major political/economical/natural event anywhere in the world to propagate across the system.
First localized random flash crashes , then plenty of circuit breakers in major indexes , then market holidays across the world to stall the crash, then complete panic if nothing manage to restore the bit of trust needed to restart trading....
Without markets, no price , and without it no transactions of any kind are possible.
It would be the mother of all tragedy playing live on every screen across the world ...
So hell yeah I'm pumped
