When should long-held alt coins be sold? When to sell even when we are in profit? That doesn't make sense. Let me know if there is a suitable alternative to this issue.
I think you should sell it when you have profited from it. if you don't get a profit then you should hold it a little longer. because we are all looking to profit from all the altcoins we have bought. but there are times when we have to sell at a loss if the altcoins we have no longer have volume and the price is decreasing every day. so it is better to lose a few assets than to lose all assets.
