If it reaches a market cap of 11 trillion, those owning the 11 trillion dollars of ounces of gold will still own those ounces, Bitcoin owners will own a number.
A number that might hold its value in the minds of its owners, or a number whose value could lose all its value in the minds of its owners.
Gold even helps determine the value of those dollars that can be printed in excess and lose their value also.
Gold will still be beautiful to look at, or at least have physical uses.
Yes, but it's not a zero-sum game. You can convert BTC to gold, or silver, or real estate, etc.
How much of your wealth is no more than a number? The amount of physical money (dollars, coins....) is dwarfed by the number of dollars that are claimde to exist, but in truth they only exist as “1”s and “0”s in a computer.
