What does bearish mean?

What does bearish mean? Investors who believe that a cryptocurrency price will decline are said to be bearish.

In addition, when the cryptocurrency markets (or individual cryptocurrencies) are in a downtrend the entire market (or that single cryptocurrency) can be considered bearish.

Even in bearish markets there do remain some bulls (the optimistic counter-parts to bears), and as time goes by the pendulum will swing from a bearish sentiment to a bullish sentiment, and markets will begin rising again.
