Because nobody knows when the market will start to rise. But, as I expected, this time not from Sales just stopped and watched the market and appreciate this time with I family on the grounds that in a few months the market will start to rise. So this time there is no compelling reason to offer. I don't know myself and I can't predict the increase. But if the coin that I hold is valid and worth holding, I better hold it or I have to cut my losses.
The market is very sensitive at the moment and no one is coming forward to make confident prediction these days too. Although I would say cutting the loss time is already passed if you invested in early 2017 because now the altcoins most of them are down by 70 -80 % so does not make sense to cut loss.
If you invested afterward and down by 30-50% then you can cut losses because there is high possibility of seeing new lows for most of the altcoins.
