Four year is too much for some people, some people can spend 10 years and remain to be a newbie because they are only hearing about most but they do not know what is going on and the facts but for someone that are into crypto for 4 years, study the market and know many things, they will not be called newbies. I am getting what you are saying but we have to consider that people have different cognition and some people learn the past very fast to know the right direction to take.
