Investing in any currency is an activity that, roughly speaking, can be done in two ways: the speculative, by means of short sales (buying and selling currencies several times in one day depending on the possibilities of the price going up or down), Or by developing a medium- or long-term investment scheme (i.e buying currencies and saving them for a longer period to sell them when appropriate).
No, the successful trader is not me. I’ve gotten lucky a few times and I’m still refining and trying out strategies; on the other hand, I’m part of communities of people who trade on a daily basis to grow their portfolios, and while some of the results can be attributed to luck, a majority of it is based on fundamentals, good habits, and experience.
