Just a hint: Litecoin's volume on many chinese exchanges, which I know is what you're referring to, is faked. Many of those exchanges have 0% trading fees, so users just use bots and trade back and forth with themselves to create the illusion of volume.

Also, the name "dark" coin" in Mandarin(Chinese) is not Devilcoin. Whoever told you that is "FUDing"/lying.
