It is so good to look from the future when you have already lived all the ups and downs, but you need to understand how to operate in the current recent times, when bitcoin is also falling.
I am working only 1 year using Bitcoin, so I still study the opportunities I can get in the future. It's difficult to choose the best way of getting profit.
I'm still a beginner who is learning about bitcoin. I have not dared to invest using bitcoin. maybe I need to ask the person who really mastered it.
