I also want to emphasize that the strategy to use for this intention should not include other cryptocurrencies if they are truly well prepared for such, bitcoin reserve is what must be considered and not crypto reserve that may constitutes other altcoins, so they don't fail already right before starting.
I doubt if the strategy is going to include other cryptocurrency apart from Bitcoin, although there are some other cryptocurrency that they have ceased which is in their possession but that doesn't primarily mean that they are going to buy centralized coins to add to the reserve, I doubt if they are that foolish. What I suggest is that they sell off the other altcoins that they have In their possession and use it to buy more Bitcoin to add to the reserve.
the bitcoin reserve is just for bitcoin (once legalities of forfeiture and ownership are settled that it is declared 100% us gov property)
other assets will go into other pockets of investment portfolios.
such as US fed real estate will go into what they call "sovereign wealth fund"
such as altcoins,stablecoins, tokens will go into "crypto stockpile"
both the sovereign wealth fund and the stockpile will have sellable/tradable/accumilatable assets. which can then be used to hoard or sell to draw down national debt, enter treasury to pay for public services or buy bitcoin.
I really do not think they should sell some gold to buy Bitcoin, rather should use the money from the country's treasury.
they wont want to use treasury money untill they can get the treasury budget straight and not incur losses due to the debt burden and revenue vs public service expenditure deficit sorted
as for gold investment and strategy(long term)
keep in mind and for emphasis of the long term investment strategists:
imagine a scenario in 20 years without mars colony plans those thinking gold will be 6x of todays price(much like last 20 years growth($500-3k))
now thinking with mars colony and mining scenario included that gold may only max out at 2x of todays price as a ultimate ATH in future and then correct down to become cheaper than even todays price
..
think about it if it costs say
$1b for a return flight of 100tonnes from mars. then that is 3,527,400ounces per $billion, which is $283.50 per ounce for the earth-mars-earth journey
and because mars is an untapped resource where robotic(labour free) mining and refining of large nugget size gold(like the old wild west days of untapped land). the overall cost of gold mining, refining and transporting would come below $1k/ounce total(way below $500/ounce to mine/refine untapped resource rich land)
with the whole mars colony, space mining industry in the next 10-40 years booting up.. gold speculators already are planning to de-list gold from their long term 40year holdings strategy, due to plans that spaceX rockets will be bringing back 100tonnes of refined gold(and other rare metals) from space. thus kill the scarcity feature of gold with multiple starships returning to earth each year with full payloads(kilo-tonnes per year)
so long term investors are already planning this long term price of sub $1k gold in 40 years
and due to that, a second layer of economists are then planning for that 40year plan, where people are not forseeing a 6x in 20 years so they cut short investments sooner.
and third layer economists are planning on the actions of the second layer economists plans thus plan/react sooner by speculating on the others speculations to react to a sub 10 year plan as a re-reaction to th 20 year plan of the pre-reaction to the 40 year plan
all in all some people now are thinking if they want to wait out a 10-20-40 year 0.5x 2x 6x return.. or invest/divest now/sooner before anyone else and instead invest into other possible long term investments that can yield more then 2x-6x in 20-40 years.. but do it and act on it before the others do.
EG with no life on mars to have turned to oil. will oil be the scarce resource of 10-40 years to want to invest in certain financial options. or things like crypto
in short if you were planning 50 years ahead for the national wealth of the country in the years 2070.. what would you see as a better thing to hold now to play out over the next 50 years
