Is it profitable to buy skins?

Hello! Tell me, is it profitable to buy cs go skins, or is it a waste of time? A lot of people say it's a great investment, but I don't see how that's possible.

I haven\'t yet figured out how good this investment can be, because this is a new topic for me. I still haven\'t figured out the cryptocurrency, so what can we say about cs go skins. I buy cs go skins, for example, this is the skin at this link https://dmarket.com/csgo-skins/product-card/m4a4-neo-noir , but for me it is more like an interaction with game content and a way to diversify the gameplay, nothing more.
