Bitcoin wallets linked to Mt. Gox hacker Aleksey Bilyuchenko have transferred 1,300 BTC (~$114M) to unknown exchanges in the past week, continuing a controlled selloff that started months ago. These wallets still hold about 4,100 BTC ($360M) which may be liquidated gradually, adding to existing whale selling pressure on Bitcoin markets facing their weakest year-end performance in seven years. The selloff and significant ETF outflows have created heavy supply resistance, capping price rebounds and prolonging consolidation conditions into early 2026.
