True.
In Bitcoin mining, the difficulty level of mining adjusts automatically every 2016 blocks, or roughly every two weeks, based on the computational power of the network. If there are more miners and computing power on the network, the difficulty level increases, and vice versa. The goal of adjusting the difficulty level is to maintain a stable rate of block creation, which is about one block every 10 minutes in the case of Bitcoin. By adjusting the difficulty level, the network can ensure that new blocks are added to the blockchain at a consistent rate, regardless of the number of miners or their computational power.
