As far as i know g2a has implemented the payment method through bitcoin last year so this time steam, hope the price of bitcoin will be increased more, will it?
Definitely.
When g2a implemented bitcoin there wasn't a huge increase of bitcoin price at that time, but if steam do this then bitcoin pay method will be available to millions of users which i think will buy bitcoins not only to spend but also to invest/hold.
Later this year:
Teens (without access to VISA or Mastercard) selling Steam items on the Steam Community market for BTC.
Bitcoin will be their first "bank account", so to speak. Way to onboard a generation.
