Scams are created by humans, and they always find ways to justify wrongdoing through blame. With bitcoin, it's like saying it's used for criminal purposes, or a ponzi game,...

Perhaps if criminals weren't bad, people who took advantage of greed would benefit,... then there wouldn't be any tension.
But it doesn't matter that on the journey of bitcoin receiving acceptance from everyone, skepticism is inevitable, after all, bitcoin still works the way it works, it's just the way we apply it.
