That's true, I doesn't mean that if you enter trading you'll just guessing the price of Bitcoin. There are things that need to learn. Just like learning how to red the bar graph of each alt coins, in trading you must know how to red each bar, you size should also consider each color and size of the bar. And the most important thing is always check it's 24hours high and low so you could check if that coins is really moving. So trading is not just learning it takes a lot of experienced.
