What does github activity actually refers to? According to this-
https://www.cryptomiso.com/, there are many project which have very active updates regularly in the github. Is it a good sign of having great futures? I have seen many coins which I count as shit projects are in good ranking according to the github activity.
To the best of my knowledge, when a project have an active GitHub account/profile, it shows how active they are and how serious they are taking their project's development. For me I believe that, for a project to take extra length of having an active GitHub account means they won't scam, since it shows a dedicated team. But nowadays, hardly can we see projects which have active GitHub account, many are just copycats, hyped projects and nothing more and the most reason why they dump without recovering. Also, in my understanding, yes it shows a project with a good future because once the team have get their works adequate and improved, they will last long term..
