It's true, but maybe not impossible to pull off. The exploit could've been purchased by people deeply connected and organized. If you split your investment and divert it enough, it will be impossible to differentiate from all the other incoming sales tomorrow.
There are so many smarter moves that probably could have been made though. The upside of this one is that we'll keep speculating for a good while (maybe forever) if it wasn't just a stupid crypto scam attempt after all.
