No, it's depends on the project. Some projects offer their coins for a low price but after it it will go to scam or the price will not goes up.
It is worth paying attention to the nuances, for example, to take WPP, which has not yet officially entered the exchange, now the price is very low, but if at the end of March there is a listing on the exchange, it will probably go up, and if the company can realize its idea and in a couple of years the price will grow up to $1, then you can get rich if you keep tokens for a long period.
