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.
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.
