I agree with you . If the transaction fee is 0%, this exchange will be difficult to maintain for a long time because almost all exchanges need to be profitable in order to continue building. Personally, I will not participate in this exchange because there is still not much clear information and the development policy of the project is still very poor so it will not be reliable for investors so it is best to only observe
They will don't have zero fees forever. As I understand 0% fees will be just for short period of time as promotional. Of course they can't do this always.
It's also true what you said is that it's certainly not possible if they apply a 0% transaction fee continuously,
and I'm sure it's only for the short term, I hope so
They need to live also, so getting at least small percentage in transaction fees is not really bad at all. That's business and if they will not do that, they should get it somewhere else. Otherwise, the longevity of the project is affected.
