Um, no. The vast majority of people even among wealthy/high-tech countries have absolutely nothing to do with MtGox, and people in the rest of the world are even more distant from it. It might loom large on the horizon for you and for a significant percentage of HN users, but let's not completely lose perspective here.

If the other post is to believed, they have around 740,000 BTC. There are roughly 12,400,000 coins total at the moment. That pegs Mt. Gox's share at 6%.

I'm sure a lot more than 6% of all total bitcoins are lost to dead wallets and such already, though. Only drives up the scarcity of the rest of em.

I highly doubt Gox's coins are "gone" though. Someone has those wallets and almost certainly is going to make a pretty penny fucking over the customer base, but caveat emptor.

I think only a select few people in a select few first world countries have any investment at all in MtGox.
