I would also like to know the reason why you prefer it over the competitors and if you had the chance to add extra options to it, what they would be.
Sorry for all those questions, but I am new to trading but I am into programming, would really like to hear what is missing.
The perfect website for all your needs is coinmarketcap! Because of the obvious reason for which it is designed in the first place. The website as you might be knowing contains number of markets and the coin can be filtered according to the merit that you want to watch for. The prices are real time and you can compare all the market for single coin at one place! Thus giving you the broad perspective of the coin which you are trading. Thats the best choice according to me. And off course to go for in depth analysis you have to aways choose the exchanger which is giving out most of the trade volume for that particular coin.
