I happened to see someone asking about the concepts of bull and bear markets in the crypto space, so I’ll share my understanding in the hope of helping beginners.

Let's start with the most basic concepts. Being bullish means expecting the market to rise; going long means buying. All buying actions in the spot market are considered going long, profiting from buying low and selling high. For example, if a coin is currently worth ten yuan, you buy it, and when it rises to fifteen yuan, you sell it, earning a five-yuan profit. That’s the complete process of going long. A bull market doesn’t refer to a specific person or institution but is a collective term for investors who share the same optimistic outlook on the market.

Conversely, the logic of going short is the opposite. Being bearish means you think the market will decline. You can't short in the spot market, but you can do so through futures or leveraged trading. Let me explain the specific process of shorting, as many people tend to get confused here.

Suppose a coin is currently worth ten yuan. You expect the price to fall, but you only have two yuan in cash, which isn’t enough to buy a coin. At this point, you can use the two yuan as collateral to borrow a coin from the exchange, then immediately sell it on the market. This way, you now have ten yuan in cash. But this ten yuan cannot be used freely because you still owe the exchange one coin.

If the market indeed drops as you expected to five yuan, you can buy back one coin with five yuan and return it to the exchange. The remaining five yuan is your profit. That’s the profit logic of shorting. But conversely, if you expect a decline but the market instead rises, your collateral will incur a loss. If the loss exceeds your collateral, your position will be liquidated, and you’ll lose your principal.

So the key difference is this: bull is buying first and selling later; bear is selling first and buying later. Expecting a rise suits a bullish strategy; expecting a fall suits a bearish strategy. Once you understand these, you’ll grasp the basic logic of the market.
