This exchange is not necessary in any case. My personal opinion, this exchange kills the coin.
I also think that yobit is not necessary. There are enough accusation against them. Anyway coinexchange will swap to new Xevan XLR algorithm on 1 November. After that dev can search new exchanges not so expensive.
I also feel yobit is not neccessary as there are a lot of FUD against that exchange. When the budget system comes alive the community should be able to vote and fund listing on better exchange as well as spend on good marketing.
