I like that we are able to trade crypto currency pairs with several exchanges while using one interface (Espy). It's easy of use if you know how it works but there are some things which take time or can be confusing at first sight when starting out. If u don't understand everything about this tool then i suggest getting your help from someone who knows what they're doing before trying yourself because once something goes wrong its difficult to get back into normal mode without restarting all over again! This was an issue we were having where certain trades would not show up unless manually refreshing our screen. With espayer it has become much easier than working around other platforms.
