A bear market in crypto refers to a period of declining prices and market pessimism, where the value of cryptocurrencies, in general, experiences a prolonged and significant decline. During a bear market, investors and traders are more likely to sell their cryptocurrency holdings, leading to a further decline in prices. Bear markets are often characterized by a lack of optimism, increased volatility, and a decrease in trading volume. It is the opposite of a bull market, where prices are rising, and market sentiment is generally optimistic.
