Mining has never been an easy job. Each block requires computational power, and miners continue to exert effort in this competition. And this is the brilliance of blockchain design — the difficulty is not fixed. The network automatically adjusts the mining difficulty based on changes in computational power to ensure that block times remain stable. When more miners join, the difficulty increases; when miners exit, the difficulty decreases. This dynamic balance mechanism maintains the security and predictability of the entire network, and also tests the determination of every participant.
