Because I like doing things the unconventional way, I decided to make a personal chart of altcoin prices on coinmarketcap.com. The chart helps me study the market behavior of coins and I've discovered that those unknown coins (XEM, DGD, EMC...) sometimes make a steady increase in price which can be tapped into.
Thanks @Das, "I decided to make a personal chart of altcoin prices on coinmarketcap.com" Can you please tell how to get chart so that we can track the changes and discover some good coins.
