If you have observed the market since Trump took over as president, Gold is doing better than bitcoin in profits which I think wouldn't make Trump to consider selling some fraction of their gold to buy bitcoin. I agree with you that Trump isn't suppose to add those shitcoins as part of US reserve. But what do you expect from a shitcoin owner, he will support his other colleagues.
We all know how gold has been performing well since last year and same do bitcoin, if you will not forget quickly that we made a all time high of $109,000 with the bitcoin market price, from here we are still moving henceforth more bullish, as the market is going and it just happened as a coincidence that they are both performing well now, but for us to make an overall assessment on their performances both, bitcoin is still a step higher than gold when it comes to profitability.
US can still not touch their gold but buy bitcoin with whatever means that US can use to purchase bitcoin, because I believe the country is rich enough to plan for a DCA accumulation method which they can use to buy bitcoin monthly, bimonthly or quarterly.
Even if they are not selling their gold now that its at the peak, which i don't know their reason on that, they can still use some other asset towards considering for bitcoin and invest.
Gold currently at ATH, this will be a good momentum for them to sell some gold to buy Bitcoin which not in ATH.
I think trading BTC/XAU could be profitable because their price moves quite different, sadly I didn't invest in XAU or gold, if Bitcoin price reach $120K-ish, I consider to sell some for gold.
If US start to sell their gold, this will make panic in gold market.
Perfect idea, because this is something they should see as an investment opportunity, gold is already high and has been on this since last year, if they can sell to invest in bitcoin and also sell bitcoin when it make another ATH before the end of the year, they may still have another investment opportunity of going back on gold to buy the dip and invest, i got your whole idea, its somehow very lucrative only if they can reason on this and consider it the best option, gold is high now, sell it and invest in bitcoin, when it also make highs then you sell to reinvest on gold when it might have been down, doing this and continue will be a great profit only if they can recognize such.
