Price should bounce back nice and quick. As far as the whale sell off goes, it could be many reasons as to why they sell, I dont get it either though, there are so many developments coming I can't imagine trying to sell any time soon!
I also don't know exactly how a whale thinks, but maybe they dump a lot when the project is going strong because that way they'll cause a dip (they know they are whales), and people are still going to invest in the project, so they buy again at cheaper prices after the dip they caused. If I were a whale and had to pick a project for that kind of strategy, I would pick one that everyone believes in, so a recovery is almost guaranteed.
