I'm ~200, so I can't tell you exactly, but I can only guess it's around 90-100m. If you can manage ~130M by the end of the event, go for it. Even if not, you don't have any resources to waste so it's win if you do make, and nothing loss if you don't. But I would try finding a few more keys to help yourself out.
