I have heard (but these are unverified facts) that even Binance made a free listing for some coins because he considered them promising developments in the field of crypto-currencies.
Exactly!
But it's hard to surpass all of their requirements to get free listings on Binance.
At first, big community needed to do votes.
Secondly, high daily volume.
Thirdly, really active project shown via products, activity of XDNA team.
And a bit more thing.
It is difficult but it makes some sense, because if you realize then Binance is a serious Exange, You have to show your project and they review it to realize that it is something big and serious I hope you understand me
