I have learned from this class how easy it is using binairesx API's, i can now easily use them in my project with ease of learning process provided by teacher Mr Jihyun Lee at The University Of London! He also has great knowledge about Cryptocurrency related stuff too! No any other downside as such so far but just waiting patiently till next batch starts because its not enough seats available yet :).
I like that it allows me access to my coins without having to go through another exchange, also they have some really cool tools such as "Bittrex bot". The only thing i dislike is there arent many people using this service atm so its hard finding support when you need them or if someone else has an issue with bnx (which happens allot). If anyone wants easy ways of trading crypto's then use binance x! There is no fee either which makes things even better!
