It is very difficult to me...I always trade in the opposite direction and lost money...
It's sad, but you're not the only one who loses his money trading. According to statistics, 90% of traders lose their money. And the fact that almost everyone writes on the forum that they trade and make a profit is just a desire to pose as a successful trader, and not a statement of reality.
I am still not really believing that number. That number changes time to time, 70% was another number that was thrown around and 90% is something I have seen before as well, you are not the first person that said it.
However, I do have hard time believing that 90% of the people in the bitcoin world would lose this much money, feels like they should be making more and I think it feels like it's something that would not be really all that much of a big deal. I hope that it is not true and this stat is just a made up one, if it is really true then I would really feel very sorry about it. There are so many people who are making so many mistakes, and having something like this doesn't really feel like it makes sense on the long run.
