Big risk ,big results, not work for every trader or investors. First you have to look at how you have skills of trading. Unless there is a trading skill, it will not take long to become a huge capital to Zero. Those who make profits by trading with huge capital they know how the market works. Inexperienced traders cannot take profit because they do not know how to trade and how to market work , do not know how to control emotions.
Starting from a small capital is very good in my opinion if you want to become a large investor who has a large capital that can generate very large profits. but if the graphics that you have are not great you should continue to study and not try with high scores.
Command of knowledge, the entities involved, the processes and correct check of numbers this all constitute to give you good results. Your idea of introducing small business and gaining experience from it is very great. This will help you in many ways as you will continue to learn in the whole journey. In this way when you will make big investment you will be more hopeful for the good esults rather than lose.
