There are a lot of details on this forum especially on trading sections but the threads are not in ordered from the newbie level to the advance, so it's better for you to search a youtube video about the newbie guide about starting a crypto trades.
Start from creating an account in an exchanges then buy your first cryptocurrency, then you can next with decentralized exchanges, different type of wallets and ETC.
Last thing you should learn and you will have your time spent most in it is technical skills, and risk management. good luck.
