What is a bull market?
A bull market is when you feel that all cryptocurrencies are rising, and the increase is huge, with almost every coin able to multiply several times.
What is a bear market?
A bear market is when you feel that all cryptocurrencies have no value, and you even think they are like air, about to go to zero.
The difference between a bull market and a bear market is the sentiment of people.
The "retail investors" in the market often have very short memories, only lasting 7 seconds. They always follow the market sentiment, completely immersed in the fluctuations of the market, lacking the ability for independent thinking.
