Long-dormant Ethereum and Bitcoin wallets are starting to wake up. Recently, one of them, containing 2,594 ETH, woke up after a 4-year sleep. The wallet owner has already exchanged 2,555 ETH for approximately $4.19 million worth of stablecoins. Another whale, inactive for two years, woke up and transferred 10k ETH (approximately $16.5 million) to Binance, OKX and KuCoin. There is a similar resurgence in Bitcoin wallets.
