With technical knowledge, there is definitely a need for psychological awareness. Technical knowledge alone cannot save an investor if he lacks awareness. If he does not have the ability to control it. We often see cases where a person knows the security issues very well but he loses his wealth due to greed. For some reason, he may have entered a site due to which he lost the wealth in his wallet. Despite being experienced, that person had to lose. Although this does not happen in everyone's case, there are many people in the crypto space who get greedy. They lose wealth because they cannot control their greed. That is why I must say that a person does not need to be very skilled in investing. If he starts investing with basic knowledge and is in the right position in his psychology, then he will be able to protect a lot of his wealth and can gradually gain more skills after investing.
You are right that psychological awareness cannot be created by technical knowledge. Many psychological issues depend on the financial structure. A person may consider himself very disciplined but if he does not invest with discretionary income he will not be able to manage the investment activities for a long time. Because if he invests with the required amount of money it can be useful at any time in the future. At that moment neither his psychological discipline nor technical knowledge will be useful anymore.
And for me the most important thing about psychological awareness is to understand in advance what his reaction will be to his decision in the Bitcoin market volatility and prepare accordingly so that he does not have to regret any wrong decision later.
Now if the price of Bitcoin starts decreasing or if the price of Bitcoin suddenly starts increasing at that time what will an investor do, what kind of reaction will he take that investor should control it in advance. Just as panic selling or over aggressively investing in Bitcoin is a mistake when the price keeps falling and also if you decide to sell your Bitcoin holdings with greedy mindset for the profit you will make if the price suddenly increases then you will miss out on the potential for more profits in the long run. Psychological awareness depends on the planning fund management, cashflow and financial situation of investing in Bitcoin.
