An anonymous Bitcoin whale continued holding its assets despite extreme swings in unrealized value, according to Arkham, an on-chain data analytics firm. The wallet withdrew $461.5 million worth of Bitcoin from Coinbase about two years ago. Its unrealized profit peaked at $315 million before turning into a loss of as much as $100 million at a low in July. Since August, the holder has transferred $82 million worth of Bitcoin to Kraken but retains $418 million worth of the asset. The position now carries an unrealized profit of about $40 million.
