why every trading I always lose. his coin's endurance for weeks went down, when I sold it, the price went up.
The reason why you always lose is because you broke the basic principle in trading and that is to buy low and sell high. Eventually what you did was to buy high and sell low. That is the reason why you are losing in trading. So just be patient and keep in mind that bitcoins value is volatile and it goes up and down.
That's the most retarded thing to say, I'm sick of noobs saying this shit, thanks sherlock, buy low and sell high HUH? You think he lost because he bought high on purpose? You have no idea what you are talking about. Go learn some Technical analysis before making such stupid comments.
