I agree with this, this is really outdated. At this point, if anyone still says that, it proves they are stupid and lagging behind the world. Or they are people who don't believe in bitcoin and now they think they missed out on bitcoin so they hate bitcoin and don't want others to invest in it like them. For these types of people, we should ignore them and don't try to argue with them because their ego is very big. Even when they know they are wrong, they still keep arguing with us, which only wastes our time.
