Thank you for your comments! I'm glad this info is helpful.
Cult, YoBit must have changed something very recently because they always had 3 listing options, one of them being free.
I thought that yobit has been charging the new coin with some bitcoins, this is my first time to see yobit doesn't charge anything to list the new coin and it seems fake for me. But yobit exchange can't be trusted right now because it has been running so many ponzi coin.
