Adjustments in cryptocurrency mining difficulty directly affect production costs, which in turn impact market prices. When mining difficulty increases, miners need more computational power and energy to mine the same amount of cryptocurrency, raising production costs. This may lead to miners selling less of their mined coins, reducing supply in the short term and potentially driving up prices. Conversely, a decrease in mining difficulty lowers costs, increasing supply and putting downward pressure on prices. However, the market also takes into account long - term factors, and price reactions may not be immediate or straightforward.
