The truth is to be successful in trading one needs enough equity. Starting with little money will not help at all, instead it will expose the trader to take high risk which may end up closing the trade. But if there were enough capital they will be able to manage risk by using low lots size and high money for trade. It will also increase balance and reduce unnecessary pressure.
Starting with little amount will help you understand that this market is very aggressive. That's the help that I am thinking and the lesson you'll gain from it is kind of helpful to you if you ever decide to pursue it.
But if it's about growing with small amounts, you'll have hard time in doing so because the market is too volatile and you as a trader that want to grow that amount might have hard adjustments from it.
