hahahah no, no need, its not really a term used for crypto only... I will venture to say it's probably very old terminology... It basically states the general tendency of movement in price of an asset. For example, we could say that Sears and traditional retail is on a bear market because every year they lose money and valuation. Their stock keeps on sinking lower....

The other term you will read/hear is Bull Market, which of course it's the opposite.

And to make sure that you become a super expert here! People's opinion on an asset, if they think a stock or coin is going up or down is expressed like this.

"I'm feeling pretty bullish on bitcoin right now"

"It looks to me that Steem is quite bearish"

There you go lima... you are officially an expert!!!

;p
