Meanwhile, it's very difficult for them to stop use of metals no matter what the law is.
What attribute do you believe monetary metals possess that is not possessed by cryptocurrencies? From my understanding, crypto is the better bet. After all, we can hide an unlimited amount of it in secure fashion.
The best bet in the long run is determined by whatever you believe makes up the base of Exter's pyramid:
Well, I believe that that rendition of the pyramid is needlessly complex. The utility of this tool breaks down when it loses the attribute of each layer being an abstraction of the layer below.
BTAIM, I would place at the apex "societal belief in the concept of money". In my mind, metals and crypto are peers in the next layer up. As neither are an abstraction of anything other than the societal belief in the concept of money.
Right now, at that layer, metals occupy a 99.8% wedge, with crypto making up the adjacent 0.2% sliver -- but growing quickly ( on a scale encompassing decades).
I personally don't see bitcoin occupying the same bottom slot as monetary metals so it would have to be one higher on the same level as fiat.
Even if you don't envision crypto at the same layer as metals, why need it occupy the same layer as fiat? Fiat is -- or at least was until 1913, 1933, or 1964 however you want to think of it -- an abstraction of metals. Crypto was never such. It does not need to be shoehorned into a taxonomy that was set in stone before its existence.
We live in a closed ecosystem and the blockchain for metals was created by two neutron stars colliding, so unless you can replicate that, it's not very easy to tamper with the metals blockchain.
If you want to go universal, you don't get to do so without the observation that the current supply of monetary metals is infinitesimally small in relation to those we will have access to in the future. OTOH, Bitcoin supply is fixed*.
. Assuming the market cap had topped out on both metals and bitcoin and you were forced to go all-in on one, which one are you going to pick?
Porque' no dos? I wouldn't know how to even start making that evaluation. Fortunately, your hypothetical is not in effect, and I cannot at this point think of a situation that would force me to make such a choice.
Anyway, as you can see from my numbers, it is difficult to advocate a 100% all-in position on Bitcoin with 0 metals even if you are a crazed gambler seeking maximum yield. If you fall in that category of seeking max yield while still having some type of safety, you would likely be something like 50% metals 50% bitcoin at most, or even 70% metals 30% bitcoin due to the risks involved. (Notice I did say you need to be a crazed gambler to have 30-50% of your money in Bitcoin).
I'm not going to disagree with your numbers. While I do disagree, there is no solid means of making that evaluation. I think you're off the mark, but have only speculation upon which to rely. As do you.
That said, I agree that is foolish to have a lot of wealth tied up in either of these asset classes without a holding in the other. I currently am biased toward Bitcoin, as I believe the potential upside is much greater than that of metals.
