Why would exchanges only make themselves available for professionals? Almost every exchange now caters to both classes. If you see Bittrex and Binance for example, they even have a basic version and an advanced version. Basic is for newbies I guess, advanced is for those with experience and who know how to use all the charts and additional information.
I totally do not see anything wrong in that, there is always class in everything and it what the system automatically requires, it is just like you saying they should keep basic 1 student and basic 6 student in the same class simply because we call it school. It will be impossible for a basic 1 student to understand what is being done in basic 6 because their brain will not be able too comprehend it.
This is the same thing that happens in in the trading market too, we have newbie and we have pro, when it comes to chart, we generally have simple chart and advanced chart, advanced chart will be too much for a newbie to comprehend, so it is very necessary they make it easy for them by differentiating it.
