Just like Jating said, nothing better can teach than experience - by means of trials and mistakes. To ease the pain, you need to research and self-educate constantly.
Additionally, you need to pick a simple and friendly exchange. In this case, I would recommend you to take a closer look at CEX. The website has not only tutorials for almost every section, but also offers its infobot, https://t.me/CexIoInfoBot, for usage. With its help, you can exchange rates and market movements 24/7 via notifications on Telegram.
