Commenting on Lady of Crypto's opinion on "making a lot of money by buying low and selling high in a bull market", Changpeng Zhao said that his own experience was buying bitcoin at the beginning of a long bear market (2014), but because there was no additional fiat currency to buy on the dip, and because of the long bear market, there was no profit to take, but it finally succeeded, and said that this method is not recommended. "In other words, I only made one purchase," Changpeng Zhao said.
