Is there any psychologist who can help traders to train their sub-conscious minds and make decision-making more sharp and efficient?
Yes, there is, and its name is "Knowledge."

Seriously, you will find that most traders rely on luck after joining the market, which is entirely wrong. What are you into, gambling? No, it's trading, for god's sake. You can't treat trading like gambling because they are different. You can't just throw a few hundred bucks in the mix and expect good returns if lucky. Please open your eyes and mind, check the market, research, and first find cryptocurrencies worth trading that can provide you with at least some profit. Then look for suitable trading windows instead of doing it whenever you want. The market isn't going to react based on your gut feelings.
The point is that traders need to know what they need to succeed in such a volatile and unpredictable market. If you strive for profits more than knowledge at the initial stage of your trading career, you are ruining your career yourself, and you shouldn't blame anyone but yourself if you fail. A significant capital and your gut feelings won't get you far. Knowledge is the key.
