I've noticed that many beginners in crypto trading overlook an important aspect—the difference between the buy and sell prices. This can significantly impact your profitability, especially if you trade frequently.

Here's the point. When you look at the order book, you see two prices: the highest price a buyer is willing to pay and the lowest price a seller is willing to accept. There is always a gap between them—that's the bid-ask spread. For example, if the best bid is $22,346 and the best ask is $22,347, the spread is one dollar.

Why does this happen? Simply because buyers and sellers rarely agree on the same price. The more participants in the market, the narrower this spread. On highly liquid trading pairs, it can be very tiny, while on less liquid ones, it's quite noticeable. When the market is chaotic or uncertain, the spread usually widens because people become more cautious.

And now the most interesting part—how does this affect your trading? Imagine you're trading a coin with a fair value of $0.35, but the bid-ask spread is $0.02. You buy at $0.36 (the lowest sell price), and can only sell at $0.34 (the highest buy price). That means the price needs to rise by about five percent just for you to break even. Each such trade eats into your profit, and over time, it adds up to a significant amount.

If you're an active trader, the bid-ask spread isn't just a theory—it's a real factor that directly impacts your results. It's important to pay attention to the liquidity of the trading pair before entering a position.
