Most projects will only display basic information which means nothing at all, just like you have read there. It happens because majority of altcoin projects are created with the sole purpose of profiting through speculative pump and dump schemes. If successful on its goal, developers and early buyers make some decent profit, while the last adopters lose money, similar to what happens in the official ponzi schemes. When informations are scarce or unclear you should skip the project and look for something more solid which has a real usage and application.
