A bull run in the cryptocurrency market refers to a period of time during which cryptocurrency prices rise significantly and continuously. During this period, there is general optimism in the market, as demand for cryptocurrencies increases, leading to an increase in prices.

Bull runs are usually triggered by a variety of factors, such as increased investor interest, positive news about the coin, or technological advancements in the blockchain space. Conversely, bull runs can be followed by a period of falling prices known as a “bear market,” where prices continue to fall.

Overall, bull run is an opportunity for investors to make big profits, but it also comes with high risks due to market volatility.
