The new Crypto Market Scanner 'Coindera' is worth checking out. It is still in beta, but has some features that are valuable. You can monitor multiple cryptocurrency exchanges and markets with both bitcoin and altcoins. You can track price changes, percentage changes, daily alerts, etc.
Also, I trade Bitcoin and ARDR, an altcoin. I make another gain in near realtime. See how I do it in this video.
