yes you can make it as your full time career because it is very profitable and easy to manage bit I would like to suggest you to take it as a part time business because here much of things can cause loss and in case of huge loss you may not remain able to invest again to stay more in Forex and you have to fulfill a lot of requirement of life through money and in situation of your bad time because of market ups and downs you should have another source of income to keep running the bread and butter of your family so just to rely on Forex business is not good by my point of view.
