What was the amount with which you started trading
I mean your very basic investment and was that your extra money or required money?
for now maybe $ 1K is enough to trade. but you better have a capital of more than $ 1K to back up if you lose.
actually there is no minimum fund to start trading dude, it all depends on your economic ability, simple if you want to earn a great income and profit you can try to allocate more funds for trading, but you also have to adjust it with your economy and your needs,
everything is relatively dependent on your wants and abilities
