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 ?
Be patient for the current red price, and better you choose to hold and wait for a more stable price. For profit then you do not rush to sell.
