You don't have to need so many reasons for this. Bitcoiners shouldn't be worried about the current dip, and any dip for that matter, because it's just a matter of time before the price will recover.

If you're impatient, then Bitcoin isn't for you. If you're fearful, just try to look at the performance of Bitcoin in all of its history. That will somehow appease you. If you don't feel assured with that, then perhaps a little knowledge of the technology assures you. If not, then, again, Bitcoin might not be for you.
