Try to add CLUD on a popular exchange like Bittrex or Poloniex
it won't happen, volume is almost 0 on yobit, and I see no activity by community. so why bittrex should add it?
Bittrex won't add it unless it gets paid 4 bitcoins, and CLUD's got zero volume on Yobit so nobody's made enough money from it to pay the 4 bitcoins. Unless something happens it will become another forgotten coin languishing on Yobit with no other exchanges prepared to add it.
