So far what I've learned, it's very difficult to find a really quality project. but there is 1 thing I think about, is where the project is advertised. because the place to market the product is very important, not only on bitcointalk but more on crypto related websites such as ico rating or coinmarketcap and others. the reason is if a developer dares to put an ad on the site is that they really want to make a big project and have the capital to start a project.
