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.
I totally agree with you on this,but the question now is ?
How about one who actually have zero or no knowledge about the crypto but have an interest on investing so as to enable Him grow more weather?
If you have no idea how Bitcoin works and want to invest in it, then you should get some free time to learn about Bitcoin and start investing once you become confident or risk a small amount and invest it with the help of your friend but keep in mind that holding Bitcoin is a responsibility and if something happens, I know that your friend will be blamed and it will ruin relationship. That's why I suggest you to learn yourself about how to create a Bitcoin wallet, what's a safe wallet, how to store your keys safely and etc... Then buy Bitcoin and deposit them to the wallet that you own (your keys = your coins).
