Spot Bitcoin exchange-traded funds (ETFs) in the US have collected almost three times the 14,000 coins mined by miners in December 2024. According to Apollo and BiTBO data, about 51,500 BTC were added during this period. Bitcoin hit a record high of $108,135 on December 17. Mining supply, on the other hand, was only 13,850 BTC. ETF demand exceeded miner production by 272%. Market dynamics predict upward pressure on Bitcoin prices due to limited supply and high demand.
