When someone can physically hand me a bitcoin and I can lock it in a safe deposit box I will give some thought to this. What happens if there is a major hack or attack on the web? What happens if the web is crashed? Thanks... but I will stick with gold for my alternative currency reserve.
What good is bitcoin if the electricity goes out?
