It depends on the coin. What is the reason of the fall? If the reason is because no one wants to buy it because it is a shitcoin then there is a low chance that it will rise again and the only possible way is if group of whales will pump it which is also have a small chance because whales don't just invest their money especially if it is a useless and have no potential. Why not just hold it until the market starts to recover? I'm not saying that you should do it but that's the best option you have if you don't need that money right now. Also research about those 3 coins that you have and if there is a continues development then there is a chance but if no one is talking about it anymore then it might be just another altcoin ready to go down on its grave.
