Bulls and bears of the crypto market, what are they?

Bulls - traders profiting from the growth of price, confident that the market will go up.

Bears - traders sure that the market is falling and selling their assets.

Bull and bear markets.

The market is considered to be a bull one, if there are more buyers than sellers.
Market participants "throw" the price upwards with their purchases, like a bull throws its prey with horns.

A bear market means that sellers outnumber buyers, pushing the price down as if a bear were pinning its prey to the ground.
