with no additional information high probability only and low probability only strategies always have a negative expected value (this is a forecasting site, not a betting site), which is why getting more information is the best strategy. Hedging is good but because of negative expected value you only want to do it sometimes. good Other strategies include betting on very new markets with no traders, and markets that are confirmed to have a certain outcome that haven't resolved or swung yet. Betting on very new sports markets using online betting odds is a strategy I use a lot.
