BobbyBigSize Shorts $ETH after Collecting $150M Gains
The trader “BobbyBigSize” has abruptly shifted his Ethereum ($ETH) strategy. In this respect, after collecting up to $150M since the end of 2024, the trader has likely turned bearish. This aggressive stance against the flagship altcoin has triggered the speculation of a likely development to take place in the market in the near term. Particularly, the trader is now holding a cumulative $70M in open crypto positions.
$45M in $ETH Shorts Indicate Notably Bearish Conviction
Specifically, a staggering $45M of this amount accounts for $ETH short. According to Arkham Intelligence, the balance history of the portfolio displays several sheer outflows and inflows, taking into account transactions involving 2xLiquidity (Proxy) and Binance, suggesting active management of liquidity. However, irrespective of the upward momentum, the conviction of the whale seems strongly bearish based on the leverage and size of short exposure. Overall, while $ETH keeps changing hands near crucial resistance levels, every trader is looking at whether the bold short move will result in a key market development.
