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.
And another thing is OP is weak handed trader,he can't resists selling when he saw somethings changing down..
The most popular and weapon of every investor is 'Patience ' and OP is lack of this thats why whatever part of profiteering he enters here,all he can achieve is failure because of this kind of attitude
