imagine not investing, when there's a huge opportunity. there is no other investment i know of, that has a decreasing supply (as cases/capsules get opened, and stickers get applied).
there are risks that skins will become untradable, and that csgo loses players. of course. still, the returns (historical, and probably forward-lookingly too) are very high even compared to these risks. because of the great returns that are expected, i'm invested. not as much as in the stock market/bitcoin, but an amount that i'm willing to lose in a flash.
imagine not investing in csgo skins, are you dumb?
