I am going to start a digital asset exchange just like binance, can I have some suggestion about anything such as how to attract users, how to improve users experience or how to administrate the system from you guys? Wish to communicate with you. 
There is always room for more exchanges, the only question is what is your go-to-market strategy. Do you intend to go Fiat/Crypto(Coinbase/Kraken) or Crypto/Crypto(Binance/Polo) or some new kind of exchange?
Touching fiat means you can access retail market directly, but you will be bound by the laws of man. Keeping Crypto/Crypto like Binance makes scaling up much easier, less compliance hurdles, and trade almost anything. What is it you want?
My personal opinion is to build an exchange of exchange (like a fund of fund or a broker of broker) if you can offer the client the ability to pick which exchange it buys from you would open a whole new world. Give it a thought or PM me.
