That's the thing with most altcoins holders, they tend to think that holding altcoins is significant but if you look at what they're holding then it's too late for them to keep on holding it.
What's wrong is when they've found it out too late and then they start to think of cutting loss. Well, 5%, 10% or 20% are still good but if it goes like more than that then it's really quite late for them to sell at losses. But I still see some few success stories that they've made the decision to sell at losses even it's too late already but then recovers with the coin that they've bought.
It's no longer good if the lost is more than 50% but they don't have any chance since holding alts is really a risk that investors and traders needs to understand, before taking any action or participating with any alt investment make sure that you are mentality and financially prepared with what you expectand how will you react in each market movements.
Not easy but instead of spending your hold asset, if you think chance of bounce back is possible, then try to keep holding till you see the market bounce back in your favor.
It's risky and they cannot revert when the loss is already too much. And those that are in deep losses, they have no choice but to hold it until there's nothing to no hope left anymore on them.
They've just accepted their losses in there and think that it's a lesson that they should learn upon investing in altcoins. It ain't easy but learning into those experiences is a must.
