Some people were wanting to trade Goldmoney GG for Bitcoin but it got withdrawn I thought?
I think Turk is right in saying that Bitcoin is less tangible than gold only because:
1) gold has a few uses other than currency, no matter how small
(but then... you might say Bitcoin has other uses by proxy - by not mining you can use CPU for something else)
2) gold is easier to visualise. The Cassius coins change that a little but not by much. Then again... what is gold if people aren't testing it properly?
However, I think Bitcoin is more tangible than Goldmoney.com - I think the private key makes it more tangible than the legal system making Goldmoney... possibly unless you have visited the vaults and meet the big minimum requirements for allocated bars.
Bitcoin's tangibility is complicated. On the one hand you have a lot of real people backing the blockchain and believing in AES256... on the other it can't really be touched can it?
It's the new way
