The Ethereum ecosystem recently saw one of the largest whale transactions in recent weeks, with Ethereum OG, which holds an incredible 736,316 ETH, or approximately $2.89 billion, depositing a whopping $500 million USDT into newly opened vaults by ConcreteXYZ and Stable.
Deposit to Aave
According to on-chain data, the whale initially deposited 300,000 ETH into Aave, one of the largest decentralized lending protocols, in order to borrow $500 million in USDT.
One entity provided most of the initial liquidity for this large transaction, representing 64.5% of the $775 million USDT held in vaults to date. Such dominance creates both excitement and concentration risk, as the initial stability of the vault currently relies primarily on the continued participation of one player. The continued collaboration between established Ethereum whales and new DeFi infrastructure is demonstrated by this event.

Additionally, it signals a potential resurgence of whale-level ecosystem activity that was missing from the Ethereum network during the recent market downturn. If this action creates confidence, other whales and institutions may be persuaded to return to the DeFi lending process.
Bitcoiners haven’t missed the memo
Around the same time, another on-chain anomaly surfaced, further deepening the conspiracy. Bitcoin miner wallet 18eY9o, which had been inactive for over 14 years, suddenly became active. After mining 4,000 Bitcoins (currently worth about $442 million) in 2009, the wallet moved 150 Bitcoins (about $16.6 million) to an external address. The funds, mined in the early days of Bitcoin, were integrated into the wallet in 2011 and have remained untouched since then.
The movement of the billion-dollar Ethereum whale and the reactivation of Bitcoin miner wallets from before 2010 both point to a potential shift in mindset among early adopters of cryptocurrencies. Whether intentional or coincidental, these actions signal the re-engagement of some of the most experienced and wealthy crypto players, raising the possibility that something important is going on beneath the surface of the market.
