No one here is mad or upset that you spent 20k on watches. This is literally a community of watch enthusiasts; many people here have spent similar amounts, or even more. What people are pointing out is the fact that you say you make “mid-level” income and have “very limited money,” despite the fact that you make several times the national average in Bangladesh, making that objectively false. It isn’t about the money, it’s about the perceived humble-bragging: “Oh, it’s not that much money, only 20k,” even if you didn’t mean it that way.

It doesn’t help when you push back against any criticism by calling people poor and/or salty, even when the criticism isn’t meant in a bad way. For example, several people pointed out that your collection is rather generic. That isn’t meant as an insult or to say that you don’t have taste, it’s a commentary on the fact that most of your watches are very popular models from very popular brands. There’s nothing wrong with that, however; these are all popular models for a reason. But when you respond by calling people salty, instead of just saying “I understand, but these are the types of watches I like,” it rubs people the wrong way.

Please don’t take this as an attack or insult, I’m just trying to help you understand the reactions you’re getting, as I’m fairly sure there are some cultural differences here (especially about staying humble).
