There is a sense of satisfaction and pride that comes with knowing how to do stuff yourself. Something called self-efficacy. Before I go on I want to believe that what you mean is the regular crypto trade and not P2P. What I can say about trading Bitcoin yourself is that you get better through your wins and losses. It is a learning pathway for you. But when you do it through a friend including copy trading which some may argue is the best, you remain at the beginner trader level for a long time. A total waste of time and resources in my estimation. Trade your Bitcoin yourself through the rigorous process of learning or just hold your Bitcoin.
In agreeing with you and in further addition, doing it by yourself serves your assets privacies and also foster your personality as an investor an independent one where you are privileged to do it all by yourself without relying on anyone.
Although it is necessary to consult a friend at a point of encountering hard times with your trading but while your friend has also given you the hints, do not take it a 100% to be relied but also consider doing research in comparison to the clues of that your friend because some friends may actually help you at your needy during the trades but with malicious minds of backstabbing you unknowingly.
