I think some of us change phones regularly because it's like a hobby to us, well to me at least. Hahahaha. I think for Xiaomi phones, the flagships models starting from Mi 9 Pro onwards have pretty decent resale value. I've seen used Mi 10 Ultra being sold at pretty good prices recently. As for Carousell, there are good and bad people over there. Some are just trying their luck and end up looking stupid. When I was selling my 5 months old iPhone 12 Pro Max 256GB, someone offered me $150 and he was serious about it. At first, I thought he was trolling me but he was serious and the usual I got no money blah blah blah story. I told him if he can find the same phone for $150. I'll buy 10 sets of him. Even the 128GB is ok. Some people really no sense of shame and super thick skin. Hahahahahaha...
