There are many sites which got the price tracker, but the thing is that if you are to get proper idea then it is MUST to have proper guide with all the tools and stuff. For Forex/Stocks, it is generally Bloomberg that you look at, but for Cryptocurrency price charts pls advice which sources to be checked??
In the days I've been trading altcoins I used cryptrader.com for more charts.
Another great option is bitcoinwisdom.com, just there the number of coins listed is rather small.
