According to @EmberCN, trader AguilaTrades experienced a significant reversal in a $400 million crypto position. Initially, the position had an unrealized profit of $32.91 million, but after increasing the holding to $400 million at an entry price of $111,713, the position not only lost its gains but also turned into a $4.1 million loss. This event highlights the risks of high-leverage trading and may influence BTC market sentiment as large players face drawdowns (source: @EmberCN).
