yes and no, maybe they bluff but on their twitter they posted a picture of binance. actualy i think they rather not post such thing before it get listed, but i believe zero have a futur. its jus my opinion thats why i have invested in. i dont need source or proof. many coins have "proof" of devs exist, devs pictures, devs past , big proof of their skills etc like bcc and another but thats not a garanty. we dont know who is satoshi nakamoto, we have never seen his face and dont have a proof of his existence but btc is a succes, the only proof people need is believe in something. and you know, if we will have a proof everybody will almost knows but we dont. its like lottery my mother always say she dont know how to play and i always answer her, nobody knows.
