I think small investment does make sense for new investor that are new on investment, investing huge amount of money without any experience is a very risky decision to make as he could have a high chance to lose large amount of his money due to bad decision made.
yes that is the good decision for new investors to make small investment first of all and after that when they gain some experience and skill about the investment site and gain some knowledge about the scam investment sites then after this they can invest large money and can do big investments which will proof very profitable for them.
