Currently, publicly traded bitcoin mining companies mine at a cost of $10,000 to $15,000 per bitcoin. Once the halving occurs, these costs will double, bringing the break-even point for miners to $20,000 to $30,000. "If bitcoin doesn't seriously exceed $30,000, many of them will probably mine at a loss." Wall Street giant JP Morgan predicts that the cost of mining each bitcoin could be as high as $40,000 after Bitcoin is halved.
