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.
When Bitcoin is less volatile, it is safer to trade with a small profit. Trading is a risky business so holding long time rather than trading in a strong currency like Bitcoin is a good idea. It is possible to get good profit by trading coins other than Bitcoin but they are very risky. So I think if risk is to be taken then risk should be taken where there is more profit. Bitcoin should only be held in holdings. Then it will give huge returns in future
