A significant number of traders were liquidated as the price of Bitcoin dropped to $25,300, raising the question of whether retail traders were the ones most affected. While professional traders often have an advantage in predicting price shifts, they are not immune to financial losses. Margin trading data from Bitfinex and OKX suggests that professional traders were caught off guard by the sudden price crash. The high margin long positions on Bitfinex and the high lending ratio on OKX indicate a bullish sentiment among professional traders prior to the crash. Additionally, futures data shows that prominent BTC traders on Binance and OKX had a long-to-short ratio that peaked just before the price correction. This suggests that professional traders were not prepared for the negative price movement and likely did not profit from it.
