According to ChainCatcher, The Data Nerd monitors that 8 hours ago, the whale address starting with 0xf83 sold 250,000 UNI (US$1.49 million) to Wintermute through over-the-counter (OTC) transactions, and currently still holds 468,000 UNI (US$2.76 million). The whale acquired these vested tokens two years ago.
Shortly afterwards, Wintermute deposited 100,000 UNI (US$598,000) to Binance, causing the price to continue to fall.
