Xiao Xia and Tony made a lot of money in the cryptocurrency world, but they like to curse! Remember that Xiao Xia, who is worth 100 million, values a second-hand Redmi phone (possibly around 1000 for second-hand). He put it up for sale on Xianyu, but when the buyer asked a few more questions, he cursed at them, probably calling them poor losers, saying they shouldn't ask too much and should just buy directly.
This shows that Xiao Xia has a problem with his character. If you, with a net worth of 100 million, care about a second-hand Redmi phone worth around 1000, then ordinary people buying second-hand phones on Xianyu value that 1000 even more and hope to buy a suitable second-hand phone, asking a few more questions. Perhaps Xiao Xia didn't clearly write down the phone's specifications and details about its condition, and when someone asked a few more questions, Xiao Xia went on Weibo to curse at them.
