Before you step into real trading I would use one of the many demo sites that are available. You can practice with "play money" before you step into the deep end with real money.
The biggest tip I can give you is be patient. Don't fall for the sudden spikes and keep low buy orders just in case the price experiences a flash crash. Honestly though, it's very difficult to make consistent profit trading and not many people can do it.
True, well but if you want it go for it. Anybody can trade but not anyone knows how to do it properly with some build up strategies. For now, you should know the basics of trading, you should understand and learn how it works. There's a lot of sources where you can learn like Youtube, it will be a big help for you as a beginner. Also after learning the basics make sure that you have jump to market risks, it is a must to know these stuffs for a good trading. You can try it with small amount and observe what will happen so that it will serve as your guide to your next trade, you will have enough knowledge and experience to it and someday you can create your own strategies and become a full time trader.
