#以太坊行情解读 has an interesting arbitrage idea. Shorting to compress the price is the first step. Once the price is driven down, the Spot becomes cheaper, and one starts accumulating chips at the low position. Then, take the opposite position and pump the price upwards. When the Spot price rises, the low-priced chips held will gain value, and finally, dump at a high position to lock in profits. It sounds simple, but in actual operation, one must consider variables such as market Depth, capital volume, and market sentiment. Especially in a highly fluctuating market, if the timing window is right, it means profit; if not, it means being played for suckers by the reverse. Some people frequently switch between Spot and derivation, playing this logic.
