Didn't expect USD1 to go viral in this way. Today, various traditional media accounts pushed the news about Bitcoin's flash crash to $24,100. In reality, it was the BTC/USD1 trading pair that experienced a momentary wick the day before yesterday. Currently, the exchange hasn't hidden the abnormal candlestick. The trading pair only has a daily volume of $67 million, which is just 1/15th of the neighboring USDT trading pair, likely caused by poor liquidity and depth.
