Tux exchange delisted BCY because people were making lot of small deposits and it costed more for them to pay transaction fees than they got from trading fees. Well, it was small exchange anyway, but now we have only Zaif where people are trading BCY against JPY, besides Counterpartys decentralized exchange with almost none volyme at the moment.

I dont know if users should collect funds for listing, I cant understand why Bitcrystals team cant get their coin listed somewhere when they are well known in industry.
