The price barely moved, so why did account returns differ so much?

In cryptocurrency trading, many people focus on how much BTC has risen or fallen, while overlooking a more important question:

With the same price movement, why do some people make more, some make less, and others lose money outright?

The answer lies not only in market movements, but also in leverage, position size, and trading costs.

Let’s look at a simple example.

Suppose your trading account has 1,000 USDT.

Scenario 1: Using 2x leverage

You use 1,000 USDT as margin to open a position worth 2,000 USDT.

If the price rises 1% in the direction you anticipated, your theoretical gross profit would be about 20 USDT.

If the price falls 1%, your theoretical gross loss would also be about 20 USDT.

Scenario 2: Using 5x leverage

You use the same 1,000 USDT as margin to open a position worth 5,000 USDT.

If the price rises 1%, your theoretical gross profit would be about 50 USDT.

But if the price falls 1%, your theoretical gross loss would also be about 50 USDT.

Note that this example does not yet account for trading fees, funding rates, or slippage, nor does it consider risks such as liquidation.

The market moved by just 1%, yet the two accounts’ profits and losses could differ by a factor of 2.5.

That’s why reading the market is only one part of trading.

Three other factors also have a real impact on your account’s results:

1. Leverage: It magnifies your position—and your profits and losses.

Leverage can make capital use more efficient, but it does not automatically improve your win rate. The larger your position, the greater your profit or loss is likely to be from the same price movement.

2. Position size: It determines how much a price change actually affects your account.

Even without using high leverage, investing too much of your account in a single position can lead to significant losses from one adverse price movement.

3. Trading costs: They steadily eat into your final returns.

Trading fees, bid-ask spreads, slippage, and funding rates where applicable can all make your actual results lower than your initial calculations.

So when reviewing a trade, don’t just ask:

“Did I get the market direction right this time?”

You should also ask:

* What was the actual position size?
* How much would I lose if the price moved against me?
* How much could I actually earn after trading costs?
* Is the potential loss on this trade within what I can afford to bear?
