Coinone exchange comes into business in the year 2014. This exchange was hard for Me to navigate across, I have to invite a translator for easy understanding of the exchange. Also, I was impressed on the liquid and trading volume of the exchange, so I decided to check out for how it operates, if it will come to my satisfaction, but I was not really impressed to use the exchange. Also, the registration on this exchange is time consuming as you must carry out a KYC verification before you can be guaranteed 100% sure that your account is safe. The telegram is active till date, and gas many members. My experience with the exchange was quite okay.
