> not a great deal
you mean like everything in www.bitcoinstore.com, and also gold and other PMs ? Which can then trivially be redeemed for cash ?
Noone will dump 1 Megabuck on a market without rebuying later, because it is NONTRIVIAL getting 1 Megabuck TXed to your bank account; (go on, try it).
What is trivial, is buying a few 100s grams of gold. At a significant markup, but gold is valued much over the "official" rate anyway, on the street.
This is quite real I assure you - and people give other people hundreds of dollars for 1 BTC not because they lack confidence in BTC -- IT IS BECAUSE THEY LACK CONFIDENCE IN DOLLARS.
In case you haven't noticed, we have impending US dollar currency crash, and people are starting to get clued in.
