This reminds me of the epic "I'M HODLING" thread

Anyways, I agree with you that everybody who sells now is just losing money. I will never sell at a dip, because it's just stupid. It's actually a good opportunity to buy more and then wait until the situation stabilizes.
Altcoins are falling even more than Bitcoin right now, so it might be also a good idea to change some BTC for alts now.
