Even if i don't like binance and their useless blockchain, infact the pair is agaist their coin

still it may be beneficial for dusk as an advertisement and to get to know what they do.
The fact is Binance is the biggest exchange and their blockchain is getting big traction so i think its a perfect starting point for Dusk. Crypto community is waking up and they are doing the right thing to jump back on the train early.
The exposure on Binance chain is probably better than being an ERC20 token. Longterm we will have to see.
