There are some articles on BitDegree (https://www.bitdegree.org/tutorials/cryptocurrency-trading/), Cryptocurrency Facts (https://cryptocurrencyfacts.com/how-to-trade-cryptocurrency-for-beginners/), Finder is also good (https://www.finder.com/cryptocurrency/trading), Hackernoon (https://hackernoon.com/the-cryptocurrency-trading-bible-43d0c57e3fe6), and TheBrockBackPacker (https://www.thebrokebackpacker.com/investing-in-cryptocurrency-trading/). But to me, trading is 10% of skills, 10% of luck, 10% of patience and 70% of emotions.
