Nope, people here on forum want things for something between 50-60% discount and paying full price is out of question. if Steam is not willing to give away half of the price people here won't be interested in buying directly (I'm not even sure if steam still takes BTC...)
you were living all the time under a rock to not know that steam offer up to 75% discount, in concomitance with festivity such christmas, halloween etc...
and yes they still accept bitcoin, via bitpay, you just need one confirmation and your order will be delivered without problem
the times I used them I needed no confirmation
i think they changed their policy, because at the beginning it was the same for me, but recently i bought a game and it was in pending status until the first confirmation happened
With some transactions being double spended its a must to take some measures to protect them, if they were letting the purchase to be made instant they were taking a risk, even small but a risk, anyway gamers are more happy for sure, atleast now i consider to buy steam to play some games i do like.
