If I lost most of my capital in one coin, I will hold the first to coin it up again, whether it can be called trading or not?
Give your opinion

If you do lose a lot of value, then hold is indeed a good choice and waiting for the coin to rise again,
It's the right strategy to employ if the market is not against your expectation.
Looking at the market now, it reflects a bad condition, coins value are not growing so we need to be more patient.
I'm saying more patient because it already requires high tolerance since it's almost a year already that crypto is not profitable for bullish people.
trading or not is not the main problem in my opinion, the most important thing is how you make a profit from it and how do you learn about cryptocurrency.
You also trade in order to have profit, it's the main action that we have to do, but what is important IMO is on spotting the right timing.
