there are many reasons for those who sell altcoins so fast or take losses, but if I personally will not sell losses unless I am pressed for economic needs. I believe that the altcoin that I have has great potential so I will hold this for the long term.
Well said, we only sell if we have no option but to sell, there are times that life is tough and that's really happening.
The reason why we hold is to see a good profit, when I say good it should be something that satisfy us as an investor, and therefore we have to be strong enough in holding it since any time the market could dump, but it will always pump afterward, we should think that way so we will not loss hope.
