If you can't hold onto profitable trades, it's like a tiger with its claws and fangs pulled out, losing its ability to attack and becoming a lamb ready for slaughter. No matter how well you defend, it's just delaying the inevitable margin call; sooner or later, you'll be meat on the chopping block, and destruction is the inevitable outcome.

If you can't cut off losses, it's like a bottomless bucket that can never be filled. An attack without defense is suicide. No matter how many times you earn 100%, if you lose 100% once, you go to zero. Without proper defense, destruction is also the inevitable outcome.

Holding onto profitable trades is offense,

Cutting off losing trades is defense.

One hand attacks, one hand defends,

Both hands must grip tight, both hands must be strong.
