What cryptos are all talk no action?

Many cryptocurrencies have a big issue with being able to fulfill their promises. Some more so than others. Which crypto in your opinion has made too many promises and is too dependent on what the creator or team says? I want to see different perspectives and not just blindly invest into words and promises instead of a technology that is actually delivering. I kindly ask that you try to answer this objectively as possible instead of bringing in a bias that you might have against a certain crypto for other reasons. Really not trying to create even more of an echo chamber than there already is on this sub lol. People should find out about potential issues before they potentially delude themselves into thinking that their project is the best. If you have concrete evidence that a project is all talk and not delivering that would be greatly appreciated.
