Yeah, that's pretty much my approach too. Those who panic always lose, don't be like them, be cool and wait. Bitcoin will rise, from the ashes, like always. Personally I'm surprised that it's still under $600, but well, we'll wait.
It is like a game of waiting. I do panicked when I first met this lovely coin. Invested money in it then see it go up, exchanged it to fiat. It rises more and what can I do? Nothing just face palm. Ergh.
At initial stage everyone will go through the same phase, but over a period of time we can learn from the things around us and can take actions accordingly.
