It is also important to understand that the market can change dramatically. You should know that even if you "read" the market, it cannot be predicted for sure. Therefore, always consider the risks before investing. This is probably one of the most important parts of investing. It is also important for you to understand that you can lose your money, so you should not invest the latest savings in any currency.
It is important to never marry an idea when you are trading, you may think the market is going down but if it keeps going up then you need to simply accept that you misread the market and it is time to change your posture, this is not the same as FOMO, you are just acknowledging the changing nature of the market, just look at what it is happening now, just a few days ago people were predicting bitcoin could reach 12k or 13k and now just a few days later sub 8k prices are a possibility once again.
