The 'Mr. 100' Bitcoin wallet, previously rumored to belong to a mysterious whale, has been confirmed as a cold wallet controlled by the South Korean exchange Upbit. Onchain analysts and blockchain explorers, including Arkham Intelligence, have verified this information, debunking the myth that the wallet was used for strategic BTC accumulation during price dips. The wallet holds approximately 59,335.54 BTC, with regular 100 BTC inflows identified as routine exchange activity rather than stealth buying. This revelation highlights the potential for misinformation to distort market perceptions and mislead traders.
