I totally agree with this statement.
Most people come to trading because they want to make money easily, sitting at home. The thing is that not all of the newcomers have enough money to live on forex trading. Technically, it is possible to make a million dollars out of a hundred in a year but it is very unlikely. The chances are the a person who has only $100 will lose all the money within a week because in the chase for decent money, he/she will forget about risk and money management which will bring him to nothing.
On the contrary, if a person starts with $10,000, they will be able to learn money management and they will boost their motivation every time their deal is successful because they will get some real money from them.
