I should have gained ample knowledge before getting started. The market doesn't favor anyone, so you need to understand everything yourself because you can't rely on luck in trading, but knowledge can save you from excessive losses.
I believe people who don't have a general interest in trading and financial markets shouldn't get into trading only for the sake of potential profits they can earn from it. There is indeed a lot of money to be gained from this space, but only if someone can manage it very well. If you can't do it properly, you can also lose significant amounts of money in trading.
Yeah, don't FOMO, never trade against the market, and avoid investing in pump-and-dump coins only for higher profits because the risk is too high for a newbie to handle.
Use multiple sources for any information you get. You can start from anywhere, but make sure you always verify every piece of information from different sources before reaching a conclusion. Don't rush it; take things slowly so that you don't forget things you earned earlier when learning newer things.
