This is one of the reasons I expect both a very strong bull market in Bitcoin combined with a brutal bear market in gold and other precious metals. So we could see BTC / USD in the 100,000 to 1 million range or higher and 1 oz of gold dropping to 500 USD or even below 100 USD. In effect a major transfer of wealth from gold to Bitcoin, kind of like the move from horse powered transportation to motor transportation 110 years ago.
I don't believe at all that bitcoin's rise means gold's demise. When bitcoin rises and holders diversify, a disproportionate amount is going to physical gold. I think this offsets the (also large) percentage of gold hoarders dishoarding gold to buy BTC.
Fiat is the thing I don't see anyone is interested in this scenario. It is also an instrument of slavery, because for every dollar you own, someone else is in debt the equal amount. It is shameful to have balances in most national fiats for this reason (ruble, yuan perhaps exception).
This is my strategy. Once the market value of a bitcoin equals the market value of an ounce of gold, a yet to be determined amount of my bitcoins will be sold/exchanged for gold. A small percentage mind you, as I'm a believer in the long-term progressive success of bitcoin. If something catastrophic happens (fatal flaw discovered in the protocol, whatever...), I will go down with the ship, bag in hand.
Why an ounce? Both ounce and bitcoin are arbitrary: gold can be measured in carats or grams, and bitcoins can be millibitcoins or decibitcouns or whatever. Isn't it better to compare
market caps of gold and bitcoin?$6,470,120,039,345
gold market cap
btc market cap
$ 8,249,485,143
[Apple market cap - $555.44 Billion]
Divide gold m.c by btc m.c and you get 784.305920574 (gold is that many times more than bitcoin)
if 1 bitcoin is currently $645 then if we had gold market cap, 1 btc would be $505,877.31877
------------------
doing the same for apple m.c, ($555,440,000,000 around) divide by $8,249,485,143
is 67.3302624796 (apple is this many times greater than btc m.c)
so if 1 btc is $645 now, then if we had apples market cap, 1 btc would be $43,428.0192994
