I would say so far bitcoin has had about 0% effect on gold capitalization.
Well, I, for one, have bought some bitcoins with money I would've otherwise used for gold, but yeah, obviously the impact is essentially nothing right now. When I use the word "eventually" in this thread's title, I mean, decades/generations.
Really, we have been using gold for 6000 years, bitcoin for 3. While bitcoin has done a wonderful job in decentralizing its counterparty risk, it still has counterparty risk in that it relies on multiple existing infrastructures like the bitcoin network, the internet, and the power grid. With gold you can trade where there is no internet connection and no computers. It can be instantly identified by its very high density without the need for mind boggling math, and it can be explained to a 3 year old.
Agree with kjj above about definition of counterparty risk. But your underlying point, that bitcoin relies on more infrastructure than gold, is of course valid. However, your implication that one must fully understand the cryptography on which bitcoin is based in order to understand that bitcoin has value is just silly. Humans very willingly assign value to all kinds of things they don't fully understand (like federal-reserve-notes, for example).
Gold is not just for governments and rich people. Common folk like me can buy it up a little bit at a time. I have a couple dozen oz and as such I get to hold my wealth just like the big boys do.
How does this not hold true even more so with bitcoin?
I am pretty sure gold will be the go to commodity for the very wealthy until such a time as transmutation of atoms because cost effective.
For now, yes. In say, 10yrs, if bitcoin is accepted by a decent number of merchants and the general public has heard of it, I think it won't be too strange for people to hold X% of their "hard money" portfolios in bitcoin. Maybe not in place of gold at that point, but in addition to (eg, maybe the X% of total portfolio is a point or two bigger allowing for the btc holdings). Eventually, I'm positing that people may decide that they're holding bitcoin and gold for the same reasons (except the end-of-the-world folks who will hold mostly guns and seeds anyways), and that bitcoin has the same properties as gold plus a whole lot more. Thus, a tendency to hold more btc instead of gold long-term. But who knows....that's why I'm asking the question. Curious to see if there seems to exist a good theoretical reason why that would never happen.
