It's impossible to trade without any loss, even with all the best mentor and advance trading indicators, there will still space for error and predict the wrong movement, and all success traders learn from the lost, so there is no such things as safe trade, trading means to be risky
Yes, it is true, trading without a loss is a fortune. It is impossible, in trading we will always get profit continuously. Because sometimes even a professional can make mistakes, whether it's reading charts or buying or selling currencies.
The rise and fall of a currency is uncertain, but predictable. Predictions are usually not completely correct, it could be far from what we thought. But by predicting the increase or decrease that will occur, we can anticipate a risk that will cause a loss to come.
By anticipating we can minimize the losses that will occur later. Actually we do not expect to get a loss, all traders and investors will always expect profit from what they do. However, we don't know what will happen in the future, so prepare at least the funds to break even or sell the currency before the price drops, then buy it again when the price goes up.
