There is no reason to sell coins at this time when market prices decline, I always hold the coin that I have as a long-term investment.
Mate, your long term hodling are for long term. Keep that in mind. You would never want to sell coins which you bought at 300$ to sell then at 250$. Hold them till they reach at least 500$ or even more since its long term. Its as simple as that.
I think so . So I will not sell what I have. I believe in this market. So even if I lose everything I will not sell and I will not regret my decision.
You should buy into the dip in case you are confident about certain coins than others. Missed ICO tokens that are dirt cheap at this point wont be so after a few weeks. In fact several tokens touched all time low this week and people are loading them up.
