Trading means Buy and sell. search on YouTube and search in google (What is crypto trading) you will get a lot of search result. And read these google search results and watch the YouTube videos from where you can easily gain knowledge about trading.
Even trading is all about buying and selling, you cannot buy or sell at every price level which is the catch here and when you know where to buy and where to sell then you will become a millionaire or billionaire in short period of time hence learning and making ourselves completely ready for trading must be a very big task and we need to be highly dedicated while preparing for trading.
I agree these days we are having lots of free resources for learning about crypto trading but unfortunately beginners are not making use of them but they slowly learn after getting into trading from their own mistakes. This way, I guess OP is seeming more responsible and I hope they might have got all the needed things for their preparation for becoming a profitable trader.
