Whale Awakens: First Activity in 6 Years
According to on-chain analyst EmberCN (@EmberCN), a whale address that participated in the Basic Attention Token (BAT) ICO in May 2017 and ultimately reaped $23.77 million in profit has suddenly become active after 6 years of complete dormancy. The address started selling ETH on June 23, 2026, and within two days (through June 25) has liquidated all its ETH holdings.
The final transaction occurred 2 hours ago (June 25, 07:20 UTC), when the whale sold 15,000 ETH worth approximately $24.29 million. This brought the total sell-off to 27,586 ETH, all converted to USDS (the decentralized stablecoin from Sky Protocol, formerly MakerDAO).
Full Transaction Timeline: From ICO to Dump
The whale's journey began in May 2017 when he participated in the BAT ICO, likely at a very early stage. Between 2017 and 2019, the address gradually sold 35 million BAT on-chain, accumulating a total of 27,586 ETH. These ETH remained untouched in the address until June 23, 2026.
Here is the exact breakdown of the sell-off:
- Day 1 (June 23): Sold approximately 4,586 ETH for ~7.5 million USDS at ~$1,636 average;
- Day 2 (June 24): Sold approximately 7,000 ETH for ~11.45 million USDS at ~$1,636 average;
- Day 3 (June 25): Sold remaining 15,000 ETH for ~24.29 million USDS at ~$1,619 average;
- Total: 27,586 ETH → 44,836,000 USDS, weighted average price $1,625.
Note: USDS is the stablecoin issued by Sky Protocol, pegged 1:1 to USD.
Why Sell Now? Market Context
The whale chose to exit in late June 2026 when ETH was trading around $1,600. While this is well below the 2021 all-time high of $4,800, for this whale the cost basis was essentially zero (since the ETH was obtained from BAT sales, and the BAT itself was bought at ICO price). Thus, even at $1,625, the profit is enormous.
The three-day staggered sell, combined with conversion entirely to stablecoins, suggests the whale may be bearish on ETH in the near term, or has specific needs (tax, portfolio rebalancing, or moving to another ecosystem). Notably, the BAT ICO happened 9 years ago, and the address had been dormant for exactly 6 years (since 2019). This timing might coincide with tax reporting cycles or lock-up expirations.
Market Implications: Whale Behavior as On-Chain Signal
When long-dormant ICO whales become active, the market often interprets it as potential selling pressure. Over three days, 27,586 ETH ($44.8M) moved to the market, which could temporarily suppress ETH price. However, given Ethereum's daily spot volume often exceeds $10 billion, the actual impact is more psychological than fundamental.
Key takeaways for retail investors:
- On-chain surveillance matters: Public block explorers allow anyone to track large address movements and anticipate sell pressure;
- ICO long-tail effects: Participating in early token sales and holding the proceeds (especially in ETH) can yield extraordinary returns, but requires patience through extreme volatility;
- Stablecoin preference: Large holders typically convert to stablecoins instead of fiat when exiting, maintaining flexibility to re-enter or move funds.
As of this writing, ETH trades at $1,618, down 1.2% in 24 hours. The whale's address now shows a zero ETH balance. Observers will watch whether the USDS is subsequently transferred to centralized exchanges (CEXs) for fiat withdrawal.
