When is it cheap?
Fees follow demand for block space. Weekends and late-night UTC hours are usually cheaper; fee spikes follow market volatility. If your transfer isn't urgent, the economy tier can cost a fraction of the fast tier — and for small amounts, the Lightning Network avoids on-chain fees almost entirely.
