The Bitcoin network continues to surprise. While analysts expected a slowdown in hashrate after the April 2024 halving, the computing power mobilized by mining companies has just reached a historic record of 833 exahashes per second (EH/s), an increase of 9% in just a few days. This surge in power is explained by the massive investments made by mining companies, which anticipated the reduction in block rewards by strengthening their infrastructure. However, a surprising contrast emerges: despite a price hovering around 100,000 dollars, transaction fees are at historically low levels, which undermines the profitability of mining companies and raises questions about the economic balance of the network.
