you need to be available and to have a cash flow .. if you start wtith a low amount of money then u will spend a very long time before earning alot .. just ur guts an analyse before every move
Starting with small amount will guaranteed you small returns so if you wanted to make more money, you really need to risk a bigger amount of money upon investing into a legit type of it. And also you really need to be courage and that guts you are saying in able to accept that there is a way to grow your money in investment but also there is risk.
Small money means small risk while big money is riskier, the money you put is based on the amount that you can afford and your confidence level. The only feasible way to make a decent money here is by investment, we should be willing to take risk and make a right analysis on whatever we plan to venture to.
The risk of the investment is dictated mostly by the investment itself and not by the amount of money you put into it, if you put a bigger amount of money on an investment it becomes riskier for yourself but that is why it is always recommend to diversify your investments to avoid that risk.
