Latest data shows that BTC mining difficulty slightly increased in last week's annual adjustment, currently reaching a level of 148.26T. According to CoinWarz's estimates, the next difficulty adjustment is scheduled for January 8, 2024, when it is expected to rise to 149T, even amid the ongoing growth in network hash rate.

Looking back at the entire 2025 cycle, Bitcoin mining difficulty has repeatedly hit new highs. Especially during the September rally, difficulty experienced two noticeable jumps, coinciding with a strong upward trend in BTC. However, after the market sharply declined in October, the situation changed—difficulty saw a significant pullback, reflecting the rapid exit of hash rate at that time.

From the current trend, the network is still adjusting its balance, and miners are continuously evaluating the feasibility of ROI. The data for the next difficulty cycle is likely to continue an upward story.
