Position depth directly affects emotional response—this is the eternal rule of the market. Participants involved in a major exchange's related assets are often the most sensitive to fluctuations; they can't sit still at the slightest sign of movement. But if someone like certain individuals remains on the sidelines throughout, not holding anything, their mindset becomes much calmer—after all, no investment means no waves regardless of market turbulence. However, even just casually holding spot assets can lead to a completely different experience. Position size is the best test of a person's true state of mind.
