@DreamOn -- I don't understand the above post... ?

@Sedit... and others...
You cannot counterfeit bitcoins and neither can any government entity. IHowever - governments can print off oodles of cash that dilutes the value and essentially taxes you via inflation. Printing money doesn't make for more wealth - it simply just redistributes the wealth already represented by the current cash.... "Inflation is taxation without representation"
Gold isn't inherently valuable - nothing is inherently valuable. However, we place value on gold because it has some uses and it is rare - it's largest use is in "storing value" -- which is a strange concept. It isn't particularly useful for transactions, however. It would be a bitch to weight out a specific amount of gold and send it to someone for an item.
Bitcoin is valuable because it is useful.
It is useful because it aids transactions, like other currencies. It is merely a tool for exchange much like the dollar, and it is a tool for storing value - much like gold. Bitcoins are limited, and at some point will be much harder to get than gold.
Gold can and has been outlawed in the past. <== something to think about.
Bitcoins are useful because they can buy any product on the internet. They CAN buy gold/silver/Pt and other bullion, as well as every single product on amazon, be exchanged for almost any and all other currencies, and they also have the ability to make totally anonymous transactions and sales allowing for illicit material to be sold and bought more safely than ever before - especially online.
I'm sure other people could give a better explanation, but I think that touches a lot of good bases and gives a general idea of why it is useful, valuable, etc...
Like I said, read more about it.
I suspect that at least in next 4 years 1 bitcoin is > $500
The government will try to outlaw it.. which might cause some troubles...
