Getting an expertise on bitcoin is not something you can do early on, it doesn't matter how much you study, you need to spend years on trading for you to become a great expert on this. Veterans spend months and years making a profit by trading before they go into scalping, that should be the way to make profit and they do make a profit.
However, that doesn't mean that you are going to end up with a profit without having any sort of result in any other case. You shouldn't trade as a newbie, but there are newbies who try scalping as well, and all of them will end up with a loss without a doubt. They may try to make a profit, but we all know that they are not going to be making that profit, it is going to end up in a loss.
It seems obvious to me, because no one believes that he can spend several weeks or months on training and become an excellent doctor, for this he will need to study for many years, everyone understands this. But for some reason, people have a completely different idea regarding trading, it seems to them that they can spend very little effort on learning and will be able to earn a lot of money in trading, but this will not happen. Because this is the same hard work that requires a lot of knowledge and skills, so if you like it and want to make money from it, then be prepared to spend many years studying before you can become a successful trader.
