Ethereum Updates Today: Crypto Giants Face Off: 'Flawless' Trader Stumbles While '7 Siblings' Snap Up the Dip

The cryptocurrency sector is experiencing notable changes in whale behavior as significant investors modify their tactics in response to increased market turbulence. A well-known "100% Win Rate Whale," previously recognized for consistently successful trades, has offloaded a large share of its long positions in

(ETH) and (SOL). At the same time, the mysterious "7 Siblings" whale collective is actively buying up during the market slump, according to . These contrasting strategies underscore the varied responses of institutional investors as they navigate ongoing market instability.

Bitget reports that the "100% Win Rate Whale" trimmed 9,000 ETH and

long holdings in just 10 minutes, resulting in an unrealized loss of $19.63 million at the time of reporting. Despite a track record of nearly flawless trades, the whale now holds $116 million in positions, with recent losses attributed to sharp market corrections and leveraged bets. This development highlights the inherent dangers of high-leverage trading in a swiftly changing market.

In contrast, the "7 Siblings" whale, known for capitalizing on market downturns, has resurfaced as a major ETH buyer. As per

, the group secured a $40 million USDC loan through V3 to acquire 10,861 ETH at an average rate of $3,683. An additional $20 million loan enabled them to purchase another 19,918 ETH at $3,638 each, according to . This mirrors their previous tactics, such as an $88 million ETH sale at peak prices in August 2025, as noted by Cryptopolitan. With ETH hovering around $3,500 and the Fear & Greed Index indicating "Fear" at 28, the 7 Siblings appear to be positioning for a market rebound, as reported by .

Looking at the broader market, the outlook remains mixed. Recent ETH price swings have been significant, with support at $3,250 and resistance near $3,600, according to LiveBitcoinNews. The Ethereum Foundation is preparing for the Fusaka upgrade on December 3, 2025, which aims to improve scalability and data handling—potentially bringing more stability, the same report adds. Furthermore, StakeWise’s recovery of $20.7 million in assets lost in the

V2 breach has temporarily boosted ETH prices, as the outlet mentioned.

Despite these events, market caution remains. The difficulties faced by the "100% Win Rate Whale" have highlighted the dangers of excessive leverage. For example, one whale using 40x leverage on

(BTC) suffered a $6.3 million loss in a single day after a rapid price decline, according to . Such incidents emphasize the vulnerability of aggressive trading strategies in environments where liquidity can quickly dry up.

The divergent actions of these whales illustrate the split in investor attitudes: some are focused on protecting their capital, while others are seizing the chance to buy undervalued assets. The 7 Siblings’ recent purchases reflect optimism about Ethereum’s long-term prospects, especially with upcoming network improvements. On the other hand, the "100% Win Rate Whale’s" sell-off highlights the difficulties of managing short-term price swings.

As the market reacts to these developments, analysts are closely monitoring how whale movements will shape overall price direction. With ETH trading near key support and the Ethereum network on the verge of upgrades, the coming weeks may reveal whether this period presents a buying window or signals further declines ahead.
