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

Don't worry dude. Market price may change ups and downs. It's like a gambling. Don't fed-up with this. Please hold until the price up again.
Yeah it is called trading but the question is this why you will lose your capital in a coin. If you know that the price is low than your buying point then no need to sell. Hold for the good times. If you are a professional trader then you will better know how and when to trade positively. Dont be panic about the ups and downs in the price. It is for the time being.
