Cloak is unique for those who believe on it, particularly the investors, however, Cloak is still part of the altcoins where majority of the coins are still struggling until now. Cloak use to have a good trading volume but now it seems gone, I can't remember anymore what exchange has brought it big trading volume, I think it's bittrex, but bittrex is not as big as it was before, or as popular as it was before.
