if you are just starting to trade yes it is best if you do not put all of your money because you surely are going to make mistakes no matter how much preparation you make it is unavoidable to make mistakes because the real live market is so different from all the other practice ones
I have always said something, money is earned by Knowing , what I Know is what makes me earn money, there is no other way, so when we do things like this , we go and have an order and a ready and assigned direction, it is a thousand times to think before Accepting the Tradition of Doing and letting yourself be carried away by feelings, impulses, by what some say about: "I think this will happen..."
If we read, we have many things that we learn, we will have more Bases to operate, to be more secure and think with more bases, that is the advantage.
