It's true every currency has own effects but correlation can help to a trader in long-term and it's more effective in cross pairs. Bigger capital doesn't mean can defend a trader but with correlation, an opposite force can give enough time to deal and hold, in the same way for long holding trades SWAP makes the vital change but choosing opposite direction at least it can less 70% swap.
It's my opinion other peoples can debate with their own best experience.
