It is, of course, necessary to take into account the conditions provided by the broker, both reliability and safety, but it seems to me that you still need to pay attention to the rating of brokers.
You need to choose a broker that is as open as possible and that has a fairly transparent and extensive, and favorable conditions for trading, such as, for example, with the broker Amarkets.
If you competently approach trading in this area and choose a decent, reliable and safe broker, then there is an opportunity to really make money, and very well?
Taking several brokers for work and researching them from the inside, making a minimum deposit and trading a little, will give you the opportunity to choose the best of the best.
