The market's decline is a foregone conclusion. The red drop has left many people desperate, and many have lost 80% of their money.
As long as you do not sell your favorite coins then you will not see any loss even of 1% so do not fall in such conditions or complications. It is your decision and no one can restrict you to sell or buy, you are free to choose your selling and buying time so you should take good care of these precious decisions that are key steps towards your results. If you sell it early on low prices then better you leave it and if you treat it as long term as it deserves then you are successful.
