Steam enabled Bitcoin payment option back in past year but they had eventually remove it later on due to fee problem and with volatility specially into those times where bull run happen on 2017.
Fees sore up and they do see this as a headache.When it comes to purchases then you can still possibly do such thing.On my situation there are wallet providers which you can directly load up on steam.
For gaming aspect/tournaments.It would still take time to have this collaboration.
This is the concern, since the price are really volatile the fees are also getting higher and its hard to transact online if this problem continue to rise in the future. This can be a good idea, but yes more time for this before they see the solution, cryptocurrency will hit every market for sure.
I didn't know that Steam had an option a while back that accepted BTC. I would've totally supported it, I wonder why it's not back? I think the volatility is what makes it more interesting, it either goes up or goes down, depends on the trend.
