What about the early early adopters?? They are not like "us". We have money (fiat), some silver and gold at the bottom of the ocean somewhere and maybe a few btc. If you wanna buy something you can use any combination of the 3, early bitcoiners who were not rich pre-bitcoin don't have that option They have ended up with the majority of their wealth in btc, so if they want a car or whatever they don't have a choice they can only pay by decreasing their btc. Plus for those sort of people going from 1,000,000 to 950,000 probably isn't a big deal.
I would be willing to bet that something new that hasnt been created overtakes LTC market cap.. whether LTC is 10 cents or $10 000
I'm thinking more along the lines of your general run-of-the-mill consumer products, you know, fruit n veg, computer parts, games. That's be an interesting one - has the price affected the quantity of BTC used to buy gaming shit?
