Bitcoin isn't going anywhere for a good while. I've seen it at $5, and at much more than that. The concept of it, if anyone has read it, has no flaws in the production of new coins. Yes, it has ups and downs but everything does. It's not just for criminal uses. It's a convenient way to move 100k+ from one place to another via public airplane. And plenty of people over the years are accepting it as currency.
