Skins as an investment, I wouldn't recommend as the market can be more unstable and most the time you will either lose money or break even because the fee's will get most of it. Skins for personal enjoyment, I can recommend, i sold most of my skins off recently as im going for a valve index but now i'm changing my weapon habits as i've found i enjoy having skins more than default. Skins for showing off, Yea there good for showing off.
