A Bitcoin whale that appears to have held its position for about three years transferred 158.7 BTC worth about $10.01 million to Coinbase, a move that may signal selling. Wallet tracking by ai_9684xtpa linked the deposit address bc1q7...jvlgw to address 3JLdM...jEp9L, which withdrew the Bitcoin from Kraken on March 11, 2023 and then held it through the current bull market. The holder's estimated cost basis was about $20,000 per Bitcoin, and the position's unrealized profit once exceeded $15.31 million. If all 158.7 BTC are sold, the whale would realize about $6.206 million in profit, more than 40% below the peak paper gain.
