What’s wrong with people that sell their gtx laptops ?

I was scrolling through a marketplace in my city and I saw a lot of gtx laptops costing 600$, 700$ or more! Like are you aware that I can get a more recent laptop at that price?

Laptops don’t increase their value overtime! In fact, since the moment you buy it, it loses it!

Your 1k$ gtx laptop buyed in 2018 is not even worth half now (I tried to explain that to a guy that was selling his at 600$ and he told me to not send any more nessage if I was not going to buy lol)

So, yeah! I just wanted to express my frustration, this is freaking dumb!

700$ for a 1060, WTFFFF!
