I have made most of my money on the fear of others. It really is my main strategy. Buy when there is "blood in the streets", sell when everyone is celebrating a rally.

I buy low and stay invested, keep buying whatever I can on every significant fall. BTC has a solid foundation and long term prospects are good. My volumes are low though, due to lac of capital at the moment.
