Yesterday after the first 250 $ drop of bitcoin I exactly did what you recommended here:

I wrote:
Never never never sell your precious coins!
At that time, I still didn't know how far the drop would be, but even if I am a little bit surprised now about the speed and depth of the dump, I'm very confident for the future. And just now bitcoin is already more than 200 USD above the low. All this happend during 48 hours. So what? These cryptomarkets move almost fast as light. But we have time and we only need a litte bit patience. All will come very great. The future is ours.

Yes, no point in fretting about short term price oscillations, in the long term the market will reflect the true value of these projects
