Bang on. When push comes to shove, we are ultimately the last port of call in all the choices we make. I feel your pain about Mt Gox - the latest Bitfinex loss of $63 million has been spread across all exchange users - OUCH! When the dot com crash hit in March 2000, I lost $20 million which was 100% out of my control - a sobering lesson. All my fellow shareholders lost $10 billion. Words of "zero worth" do not do it for me but the lessons were hard earned - nothing ventured nothing gained
