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.
