Most coins have lost 50 to 80% of their value, many tokens that were financed with expensive ether may now have their funding reduced due to their holdings. Do you think many of the ICOs have sold their ether and bitcoin during the last months? What other factors are making the market go steadily down?
Chances are you just need to learn how to keep your coins and not look at the price. I do not believe that after such a surge, this market can collapse so easily. He's being killed by artificial speculation.
