I Don't mind If its ponzi but i Don't want to exit too late but not too early so When is best time to exit?
You should mind when it's ponzi but sincerely, it isn't ponzi scheme bruh. The context of your exit could be wrong becasue the technology is here to stay and not just for a while, So, there shouldn't be an exit route except for profit taken to return back again.
