Gold and other precious commodities (even real estate) have drawbacks regarding their utility as a store of value that Bitcoin doesn't have.
Value is real, but at the same time value is a subjective, human construct. Real doesn't mean tangible. The value of a bar of gold isn't inherent to the bar itself, but to what a potential holder of the bar could do with it.
Crossing the border with $1 million in gold (or real estate!) is a much different concern than relocating with $1 million in Bitcoin.
“Gold and other precious commodities (even real estate) have drawbacks regarding their utility as a store of value that Bitcoin doesn’t have.”
Everything has drawbacks, even Bitcoin. I have a friend who has not yet recovered her big losses on Bitcoin (50% from 2 years ago).
As to stores of value - that is a matter of the intent as to use of the value. Yes, you can cash out of Bitcoin easily, and take your cash and do what you want, if that is a resson for holding it.
You can also have a master bank account that gives you easy access between your investments, checking, savings and credit accounts. You can direct purchases of new investments from checking, savings or credit and direct proceeds from investment sales to checking or savings - all electronically, from anywhere in the world. Your assets stay where they are while you go where you want, as easily as Bitcoin.
As to “crossing the Border” LOL, nearly all transactions can be conducted electronically today (including selling real estate property) and return from sales can be transferred electronically, from and to anywhere in the world. But you can’t walk into a restaurant anywhere and pay for your meal with Bitcoin, but you can with cash, a debit card or credit card.
Yes, you can “take your gold with you”, as far as retaining it and its value, by using a trusted depository account, with access to it from anywhere, as far as adding to it, or selling from it. In essence, you can go anywhere, while your gold is secure without you personally physically moving it. New purchases can be added to it and sales can be made from it. Gold (and other precious metals) as an investment has kept up with our technological age. You don’t have to move $1 million in gold across any border you choose to cross as maybe you had to one hundred years ago.
