When I saw the prices of crypto currencies there is almost every coin's price fell upto 20%.Do you think this is just happening due to South Korea's ban over crypto currencies or there is other reasons for that.
I hope the condition will be back normal soon but I am worried a lot.

I dont know why cryptocurrencies are start to flow but i assure you that it is normal that every cryptocurrency are sometimes goes up and sometimes its goes down, so dont worry to that.
