The thing about all these crypto mining is that no one knows which one will pay off but like u said, if you do not try, you will not get lucky. It's all about having information about a Project, DYOR, and if it interests you, then make effort... keep trying for that lucky day. Since it's not something that requires too much of our time daily, it worth giving an attention..even if it's two to three projects to get involved with, it's a good try, hopefully one will cook
