[Machibigbrother's ETH Rolling Long Position Profits Reversed, Account Balance Down to $290,000] According to Deep Tide TechFlow, on October 13, Ember monitoring reported that with ETH dropping 4% intraday, the $12.3 million profit previously accumulated by Machibigbrother from rolling long positions starting at $1,900 has been almost entirely reversed, leaving the current account balance at only $290,000. Reviewing his trading history, during the period from August when ETH rose from $1,900 to $2,500, he managed to grow $150,000 into $12.3 million through rolling long positions. However, over the past 20 days, as ETH retraced from $2,800 to $2,400, his rolling long positions frequently triggered stop-losses, causing his funds to shrink from $12.3 million to $290,000. Currently, Machibigbrother still holds a long position of 3,500 ETH. If the price of ETH drops another $30 to $2,393, his remaining $290,000 will face liquidation.
