Let's say full priced game is 60 USD, which right now translates to about 0.13 Bitcoins. Does that mean all new games will cost 0.13 bitcoins a month from now? a year from now? No they won't. Steam will just calculate rate based on current bitcoint exchange rate, just like all other places do. That's because no one really trusts bitcoin. They just use it as an intermediary hard to track currency, which a lot of the time was acquired illegally or from shady methods.
On many non-US airports one can pay with USD. However, the amount to pay is calculated based on the current exchange rate between the local currency and USD. This is not an indication that USD is not trustworthy. It only means that the shops at the airport have their expenses and revenues denominated in another currency. At this point in time there is hardly a closed Bitcoin economy. In fact, the only ones who are really paid in BTC are Bitcoin transaction processors, aka miners. Every miner that adds a block to the Blockchain earns a fixed amount of money, denominated in BTC (25 BTC + fees now, which will drop to 12.5 BTC + fees in July -- which will remain for the next 4 years). However, there are quite some people who have savings in BTC. like I do. Do I trust BTC? Yes. I expect it to increase in value over time (so far so good, I'm up 165% on my initial purchase of BTC). However, I'm fully aware this goes with ups and downs. It's a risk I take.
But the main reason I trust Bitcoin is because it's cryptographically secured. I know BTC can't be created at a different rate than the algorithm dictates. I know there will never be more than 21 million BTC. I know they can't be counter-fitted. That's why I trust Bitcoin.
Finally, Bitcoin is way easier to track than cash money. The Bitcoin Blockchain public, for anyone to see with various Block explorers, as they are called:
