In the morning, I couldn't make $300 because of #BB趋势 , and instead I lost $16. In a moment of thought, I sold my IOTA at 0.3844, and then set a buyback at 0.3950, because it just happened to add up to over $300. I didn't expect that, just a few minutes later, all the coins had significantly increased in value, and I bought back in again. Although currently 0.3950 is a loss, it still counts as having returned over $300. Because it was rising, I thought about changing the buyback to 0.3980 midway.
