JPMorgan predicts Bitcoin will drop to $42,000 after halving
Citing recent research by several JPMorgan analysts led by Nikolaos Panigirtzoglou, the halving will reduce mining rewards from 6.25 BTC per block to 3.125 BTC. This event will negatively impact the profits of miners and increase Bitcoin production costs and affect its price, from which JPMorgan experts predict that Bitcoin will plummet to the $42,000 mark after halving. .
Analysts say that based on historical data, production costs act as a lower threshold for Bitcoin prices. They estimate the center of the production cost range is currently $26,500, and this number will double to $53,000 after the halving.
However, experts say that there is a possibility that the hash rate of the Bitcoin network will decrease by 20%, mainly due to the departure of miners because the profits are no longer attractive enough. From here, they argue the cost of producing Bitcoin will drop to $42,000, based on an average electricity fee of $0.05/kWh. Why don't they think miners will sell before the Halving at this price? Or is it because they don't mine coins
