Most definitely you are right, it is real and I have experienced it, I blew the profit and capital shortly after I made it.
It can be demoralising though bit the solution is to invest in knowledge even if initially you seem to be making a few profits hear and there.
If the beginner doesn't invest in knowledge, he might get frustrated on his first loss, because he doesn't really know the reason behind his losses.
Sometimes beginners in trading do not realize the frustration they can get when they experience their first loss because most of them are already more obsessed with the profit even though they have not received it. Knowledge before doing something is very important, especially when it has to involve money directly like trading, so every beginner must have knowledge before they experience frustration that can cause loss of enthusiasm to continue what they have started.
