I think it is possible to assume a lot of things and to consider concerning any project. Each person has the opinion in this respect. But as we see from history nobody can precisely tell that he will be in the future. And many projects which are abused even feel very well now live and further develop. At these projects already the ecosystem and it you will not remove already anywhere.
Only time will answer your question, your doubts. Only time can show us real price and real value of each project. Only time will show us real capability of developers.
LOL, you don't have to think about any time. You just know to put it in your pocket and do something else.
