So for me in this situation you can buy your Bitcoin at day time and trade it at night when it adds
But it is very important to watch at it carefully.
I don't really agree if it really guarantees that you can make money when you buy at day time and sell it at night. The market is not supposed to go up when it's evening, you can barely see the chart and there's no evidence supporting on that because the price not always went up when it's evening. But I believe that it's good to trade in night time because there's huge volume.
Bitcoin is highly volatile, and that any time of day or night, its price will never be certain. So I don’t believe in this kind of analysis, as I only trade when I know that there are possible profits coming at the end of my trades.
