I am also interested in this issue! They said that the paid listing in the last year!
As it is not typical! More like a lie ...
yobit are not quarantee listing even if they are paid.
youbit listing:
• Free - 0.00 btc - no guarantee
• Premium - 0.1 btc - 4-7 business days (no guarantee in case of compilation issues)
• Exclusive - 0.5 btc - 2-3 business days + mail alert to all users (no guarantee in case of compilation issues)
And why peoplw whine about youbit listing, yobit is coin killer, there are pumpers who make price artifictially high and then dump the, coin.
If tou are intrested of buing coin you can buy other exchanges. Or have a patience! it will take time to build up. And you can slo try to enlist coin if you think they are lieing
