The core idea
Most beginners leave cash in an account paying nothing and treat that as neutral. Accounts that pay a meaningful rate on instant-access cash exist and require no lock-up, which makes leaving it idle a choice rather than caution. Doing nothing with cash is still a position, and it is one that quietly costs you.
Bottom line
The goal is not to chase every headline. It is to build a repeatable decision process: understand the risk, compare the opportunity cost, and make choices that fit your time horizon.
