Bitcoin miners have faced significant challenges this year, as the network hash rate—representing the computational power required to mine bitcoin—continues to climb, hovering near all-time highs around 832 EH/s. This has created a notable divergence between bitcoin’s price and the hash rate.
As a result, mining difficulty has also remained close to its peak, making it harder for miners to successfully mine new bitcoins. At the same time, transaction fees are extremely low, further squeezing miner profitability as rewards from processing transactions remain minimal.
