Nice job !
I'm doing the same but for an Android application that will contain all major exchanges and coin prices + a portfolio (to track the value in USD of all possessed bitcoins/altcoins) + a coinmarketcap page which will also parse the HTML data (while no API is available).
Unfortunately, exams take tons of time, I hope I will be able to work a little more during holidays (doing something that's not aweful to use is actually not that simple...)
