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.
smart investors always looking for possible good alternatives just in case things happen so they will try small investment and not to go all in
then if they already seen potential that's the time that they will invest bigger, its should be the attitude not treating your small investment as
a shame on you but come to think of it that you are just like touching the water or trying it if its too deep or you can stand on it.
In short they do it with the right timing, they calculate very well their move and ensure that higher success rate will happen. I can maybe say I am smart in a sense that I also keep doing research before I will invest in a certain project and I can prove it myself that I have more success than my failed investment. This game is a battle of smart people, we should all be smart to turn the advantage on us.
