If the climb stops before you cashed out the bet, then the funds are burned out. Roughly speaking, press the buyback button in time before the plane stops climbing, because the multiplier stops growing.
The main thing here is not to overdo it and be able to stop the takeoff at the right moment. The height in this case is equal to the coefficient (multiplication) that will be applied to your winning bet.
The Aviator game allows you to feel like a risky pilot, and your earnings depend on the height you manages to lift the plane.
