basically it is necessary to do. if people see only bitcoin as having profit potential, then I think they are wrong. it would be great if these businesses were connected to each other. for example, if you already have a job or business that has sufficient income, doing the DCA method on bitcoin is a good thing. However, if you are currently focused on bitcoin, then I think the profit you get can make you build a new business or develop your new business. people say not to rely on one job or income, because when that source is lost, then you will fall.
