I did this to help me decide when to buy bitcoin. I don't buy a lot, and am busy, so the little I can afford has to maximize time and effort as well as budget. I try to buy extreme low, and that way I can sell anytime for profit. So far, I have never lost on a single trade. But I may only have 6-12 trades in a year. My goal is to make money on my trade, convert it back to dollars, then buy stuff.
