If the amplitude exceeds 30%, the money will be gone! Buy rise, fall 10%, assets shrink by 50%, then fall 10% again, and the assets shrink by 50% again. The first time is 0.5 yuan, the second time is 0.25 yuan, if it continues to fall for several days, plus a big dump... it's no different from getting liquidated... mainly because it's not easy to resist amplitude.
