Look at such a coin as NEO, it is now worth $10, and when the project grows, the price of the coin may well grow to $100, but I think that the price can grow much higher. If we consider less well-known coins, then you can see the XYO coin, it is now very cheap ($0.001684), but the project has a ready-made project and the price of the coin has potential for growth and can grow to a few cents.
