Frequency.
Moving the hand up and down faster increases the number of oscillations per second (frequency). The wave speed on the rope depends on tension and mass per length (not hand speed), so v stays about the same and the wavelength decreases (since v = f·λ). Amplitude only changes if the hand moves through a larger displacement.
