Should we hold on to altcoins which we have invested and see the price dropping every moment or it will be better to sell them and buy it again when the value pumps ? I have already lost a good margin of profit with the ripple I don't want to make the same mistake with the Lumens which I Hold so should I hold on or sell out ?
I think you should keep all the coins you have. Do not let you sell it now because the price is still at a low. And if you sell it now, of course, you will experience a huge loss.
