It doesn't matter if the project is cheap or not if it has massive upside potential. As an example the current price of the LINK token is around 15$ and if it reaches 200B in marketcap in the next bull run then it is still almost 200X return for the investor from here but many will say the LINK price is super high right now but these short-sighted people won't see the potential of LINK in the long run. It is all about making profit and if you are making it with some high-value token then there is nothing wrong with it.
