There have been many crypto projects with this type of act which of course shows the team have exited scam. In an active project, the team do not fail to give updates at least once in a while but staying a month without any updates shows the team aren't working on anything and not serious about the project.

Even if the project should start showing signs of recovery now, it's wise to be careful because the team might have a different opinion.
