If you are asking about the coin tracking website or app that I am currently using besides Coingecko and Coinmarketcap, I would recommend Cryptowatch which will give you the price information of all coins in one screen.
It is perfect for large screen use so it displays all Bitcoin and altcoin prices for all CEXs (customizable).
A few weeks ago I found it because @hugeblack shared it when someone asked about Muli-chart in one screen.
I finally found what I was looking for.
It is no longer difficult to monitor all crypto assets and create portfolios, monitoring in one screen with price comparisons on each exchange.
Not only that, it comes with the latest crypto news which helps in Fundamental monitoring.
And it's also available as a mobile app so it's multi-platform.
I would say this is the complete package I found and you gave a good recommendation.
But about coupling EXchange with Cryptowatch, I haven't done it yet because this is my first experience, and whether or not it is safe to connect to my personal exchange.
Cryptowatch is available for all Desktop Windows, iOS, and Android devices.
