Several sites, e.g.
Coingas, have been selling steam codes for BTC (and other cryptos) for ages.
What exactly would change if Valve would accept BTC directly? Pretty much nothing?...
I never knew that anyone was selling steam games for BTC. Steam accepting BTC would mean something for me, as i would spend some money on for example DOTA2, and Steam would earn money. This way, neather i used my BTC nor they earned something...lost/lost situation.
To correct myself...yes i knew for 1 site that accepted BTC for steam codes....they were fake.
So...Steam officialy accepting BTC would be big thing for me...on large scale i dont know but steam users do look like ppl that are much closer to BTC world than for example Overstock users.
