My understanding of the trigger on the Financial Crisis gun was the declared bankruptcy of Lehman Brothers, with more than $600 billion of assets, on September 15, 2008 (the biggest bankruptcy in US history), and the subsequent appearance on television of Treasury Secretary Paulson. It sounds to me like you were alert enough to see clear signs of this Crisis at a much earlier date. My complements on your astuteness.
As to what to do with that money since -- well, I put it mostly in mutual funds across countries and in steady bonds or in a house in a new country
Do I expect to earn a lot with that? Nope. I'm no financial genius. But, anyone who wasn't taken in by the irrational exuberance of October 2007 got out.
