why every trading I always lose. his coin's endurance for weeks went down, when I sold it, the price went up.
Then that only means that you are terrible at trading and that you need to stop for sometime before tying to be successful at trading again, also you must understand that not everyone can become good at trading, it seems easy in theory to earn money in trading since you only need to buy low and sell high but the reality is a lot more complicated than that so if you do not have the skill to trade stop it and become a long term holder instead.
