Sir I am a new person I am learning almost everything from you, I try to read every comment of yours sir. I think in the first place a person should know about Bitcoin security, Blockchain technology and what is Bitcoin. If a person knows these things then he will be able to understand why he should invest in Bitcoin. When a person can understand these things then he will be willing to invest on his own and then he will be able to understand on his own what is needed to invest. Like wallet, how to buy and sell Bitcoin etc.
