Definition
A bull market refers to an upward trend in prices for an extended period of time. As of 2020, Bitcoin (BTC) has undergone three bull markets.
Understanding the Term
In crypto, a bull market refers to the (extended) period in which the prices of assets significantly rise and/or are expected to rise.
Due to prices of crypto rising and falling essentially continuously during trading, the term “bull market” is typically reserved for extended periods in which a large portion of the value of cryptocurrency is rising. They tend to last for months or even years.
Takeaway
The commonly accepted definition of a bull market is when market prices rise by 20% after two declines of 20% each. The opposite of a bull market is a bear market.
