Investing deals with buying of a coin and holding for longterm, most times it's about buying at the private sales, public sales, IDO or during an IEO or maybe spotting a gem already trading in the market, then you invest and hold for a long-term.

For trading you have to actively spend time watching the market chart, and concentrate on buying low and selling at a higher price, trading is alot more stressful and risky than investing, that's why I would advice you to invest rather than trade.
