Ofcourse yes how can you make a big profit when you are not to start with small investment. In first ofcourse as newbie I need to invest small thing then if that site is good then I will invest big next.
Investing is nothing but only casino bankrolls but there are many other assets to invest. If you diversify your funds properly in different asset classes then your profit making changes are more in the longer run. But one shouldn't invest all your money at one time instead buy in small quantities over the time so that you will get a good average price.
