I am an ordinary person trading at Switcheo.  Very easy to use:
 - Can connect on O3 wallet and Trust Wallet (you import the privatekey very easily)
 - UI / UX is great for user experience
 - Active withdrawal and deposit (because we hold personal wallet)
 - Most Neo tokens are listed here.  Token on ETH are too few
 - Use SWH token to make transaction fee and quite cheap
 - Easy to analyze chart, clear transaction history
 - However, the biggest limitation is the liquidity because users are still quite few
 The decentralized trading exchange is the future of blockchain, I think Switcheo will thrive with their vision
