It's a while ago now that steam started accepting bitcoin and it hasn't really affected the forum from what I can tell though.
But if something like amazon and ebay would start to accept bitcoin then I'd expect to see a lot of posts about that.
Yes of course we can than expect a lot of post, it would be pretty logical if you are asking me about that fact.
The market never really changed on here because of the fact that the prices on here are more attractable because they are simply cheaper than on steam itself.
