today through the brokers you can start trading up to 5 dollars, to invest you need higher amounts of money, at this point if you start trading with so little money, it will be many days before you see great results, but if you invest large amounts of money you must be patient in the same way because sometimes the market takes its time before going in your favor. To trade you need to know more about the market, study graphs, techniques, statistics, requires more knowledge although the benefits could be good if you start with large amounts of money, in the investment you need to know only a bit of the currency and invest in favor of the tendency. In both cases, there are risks that is why it is important to use a margin of risk and learn to operate or invest in the most intelligent way
