It sounds like you're looking for a recommendation for a low cap coin that will surge in price, but which people don't know about yet. The problem is that coins that have shown huge recent growth will tend to be low cap coins, and there is usually no real reason for the price rise, in which case a dump often follows. I think you need to be careful in following up any recommendations. If something has increased in price a lot recently, often that is the worst thing to buy into.
