Friend 300 dollars, did not set a stop-loss, resulting in a loss of 2400 dollars.

This is representative of the most widespread group in the crypto world.

Let me analyze, my response is as follows:

Don't think about it, when you are hesitating whether to set a stop-loss, just set the stop-loss immediately.

Because at this moment you are in pain.

After the stop-loss, you are no longer in pain.

The struggle of whether to set a stop-loss is the most painful; once you set the stop-loss, it becomes a review and summary, not painful at all.
