But people forget that, unlike gold, bitcoins (or for that matter blocks) are not all identical. They have an age. This is bound to have consequences for the relative market price. At some point in time old bitcoins (read blocks) will be values different from new ones.
Really? So not all bitcoins have identical value? Am I the only person who read this and thought it a little strange..
With gold, it is very difficult to impossible to determine where the gold came from... especially when you collect it and melt it.
I realize now that bitcoins of different age can also be merged and spitted up. And this process destroys a well-defined relation between a (fraction of) a bitcoin and a block it originated from.
So the situation is more complicated than I thought.
