Since you are new I would suggest you to learn first. Learn how the market works. Learn about the coins. Do researches on the charts. Get to know more about the coins you will be investing on. Use your own instinct and try to figure out how the coin is going to be different from others. And always keep this in mind - invest what you can afford to lose.
These pieces of advise above are helpful. Yes its definitely a good idea to continue on trading because it will give you good profit. But first give some time to observe to get idea on how the market flows and learn the highs and lows of the coin that you wanted to invest on before you take the risk. And keeping or holding some coins are also part of trading world.
