Sincerely speaking I think at the initial stage when the dropping started, it would have been better to sell, keep the cash and reinvest to buy and HODL when it drops. But now it's a little difficult to decide weather to sell or HODL as one can hardly see a green light of the coin going to the moon. However, I will advise that you HODL because it will still rise far above where it was but when is what one can hardly tell. Although this requires patience.
