Forex was indeed a great business but not to me ever since I'm aware of crypto currency investment and it good to be inform about the necessary technique to floristh in every business setting or investment but that still don't justify ones profit level for every business accept debt at some point.
Did you say was ?
I think is will be fine because, it is still present in the world all over and many people are making good money still on it.
However, if you confirm to yourself that cryptocurrency trading is giving you good money because you know how to trade it, you can do better with forex because it is controlled or regulated and you can know what happens or near accurate speculation of price.
