The missing bitcoins are irrelevant, because no one is going to buy or sell them.
An amount of bitcoins close to 5% of all bitcoins currently in existence was just wiped away as fakes. And maybe 0.000001% of all dollars in existence. Probably not even that, I suspect gox still has the majority of its customers dolars.
Its not even clear if they are missing or alreafy circulating the markets.
You really dont get it. First of all, almost certainly, no bitcoins were actually lost, they were probably stolen many years ago. But even if they did get lost, say EmptyGox lost the keys to their wallet, it doesnt matter. What matters is that bitcoin supply just shrank a whole lot now that people who had BTC balances at Gox realize their Gox BTC's were counterfeit BTC instead of the real thing. How does that directly hurt the valuation of the real thing? Again, if it turns out the US secretly sold all their gold 50 years ago and Fort Know is empty, or their gold reserve was swallowed by a sink hole, would you panic sell your physical gold?
Ppl have gotten so used to bashing fiat that u forget to calculate it in the bigger picture. U forget that bitcoin price depends on fucking fiat buying and sell it.
The gox dollars are probably safe for the most part, but even if not, they represent a very small percentage of the bitcoin economy and ~zero percent of all dollars out there. And what you seem to forget is that the price also depends on people with ACTUAL non counterfeit bitcoins. These just got a lot rarer than we thought, and those people probably a whole lot more reluctant to trust their BTCs to an exchange. Good luck replacing your counterfeit BTC with real BTC at a steep discount, you wont get mine.
