What stop loss means in crypto.

A stop-loss is an exit level that closes a trade when price reaches the point where the original idea is no longer valid.

Its job is to contain the downside and keep capital available for the next setup.

Without a stop-loss, many traders keep holding because they do not want to admit the setup failed. The stop turns that emotional moment into a planned response.

The most common mistake is moving the stop farther away after the trade is already losing. That protects ego, not capital.
