What you talking about is called as Undervalued Coins. This is also one of the technique to gain more profits during the course of its development. Usually these coins have low values because it is what gets decided at the time of ICO sale. Thus they give away the same price ta after it gets listed and with some corrections and market dumping the prices get even lesser but thats always secure one to invest into it. Having undervalued coins means you can buy huge quantities of them and thus whenever there is price movement by just one cent or something then it could be mega change in your local currency value.
