A trader has opened a 5x leveraged long position on Ethereum, involving 31,956 ETH with a total position value of approximately $54.98 million. This move follows a series of trading activities by the same individual, who previously incurred a $3 million loss on a long Bitcoin position and a subsequent $360,000 loss on a failed Bitcoin short attempt. The trader's latest strategy marks a significant shift towards Ethereum in the volatile crypto market.
