No matter what you are thought, you must know this that to be a successful trader, it takes practice and consistency.
In my opinion, newbies are losing in trading due to their lack of experience and risk management. They need to spend some time learning more about cryptocurrency trading starting off with the basics. There are so many sources that they can find in the internet like here on Bitcointalk, Youtube, Google, etc.
However, even the technical analysis of the so-called "pros" and "experts" aren't that accurate because of the market's volatility in which the movement may depend on several factors like good or bad news, whale pumping or dumping, etc. In other words, the market is very unpredictable and we always have to be prepared in this kind of risk.
