Is trading smart or just gambling?

I placed this order a few days ago, and even though I made a profit, I haven't closed it yet because I believe it will go up even more.

As you can see, I had already planned the scenario beforehand, and I knew it would crash, but I didn't dare cut my losses. I was afraid that if I did, the price would just bounce back up and it would be as if nothing had happened.I had prepared a lot for this situation and was extremely upset.
Right now, if I feel like I've missed so many opportunities to cut my losses, then I'll never cut them again.

Trading is the most psychological game I know, and it's incredibly scary.
