Is the following scenario possible?

Just wanted to run a scenario by the community about Bitcoin price drop.

We all know that the institutional money is coming this weekend building up to the 18th. Is it possible that someone who would like to keep them away, or 'scare' the banks could have dumped a small chunk of their coins to freak out the banks? As some sort of a warning, or the message: "You guys have no idea what you're getting into"
