CDT is sad thing, why it drops so hard? I am in a huge loss.

In any market, it is not possible to keep the value changing all the time. Some times, it will take some time to regain its value, not at present there is a lot of things going with the China announcement so the price of Bitcoin is dropping and automatically other altcoins will also drop.
Yes, but it's more difficult to grow than fall dawn, so it will restored over a long period of time.
