Hello. We understand your concern and have answered this question many times in our main Telegram group chat. Here is was we can say on the matter:

a) We have emailed and or submitted applications to the top 50 exchanges on CMC.
b) We are in direct conversations with multiple of these exchanges.
c) We are currently up for voting on Huobi.
d) We have no issue paying for listing and expect to do so.
e) Immediate listing is less important to us than finding a synergistic partner (One that does not require tokens to sell).

Thanks!
