I personally don't think you know how to invest in the csgo market.

Before storage lockers, I'd make alt steam accounts to hold all my items.

I am buying cases for $0.04-.$010 then reselling them for $0.60 - $1.10.. That is huge profit for me. I've increased my money by 14 times.

Buying cases and opening them isn't investing, it's gambling.

Yes, putting money into the steam market is devaluing your currency, but if you don't need that money at the time and can wait it out for a couple years then you're basically getting free games assuming you've invested in the right items. Even if steam money is still less valuable then usd, euro etc.. You're still going to use your currency to buy games with it.

I don't think it's exceedingly rare, I just think you need a plan before investing in the csgo market and have to understand that what your buying won't be used for buying groceries with.
