Guys, I have a question. I want to buy a currency at a lower price, but when it rises, I sell it. Why does it drop again? Do I have to keep the currency for less than 24 hours? Because every hour at 3 AM the currency returns to its original value. If I don't sell it, my balance decreases according to the drop.
