That is stupid.  It is stupid to think Bitcoin would help in any way strictly with the repayment of the U S Debt too.  It is as if they were gambling Bitcoin to try and win the Jackpot.  But instead of retiring, the end goal is to repay the Debt.

It does sound very Bullish even if that is the only reason they would buy Bitcoin for.  It means they Trust Bitcoin so much that they think it is going to help clear the Debts of one of the strongest countries.  But the country deciding to sell Gold to buy Bitcoin sounds plain stupid.  They could both be Reserves, but Gold is pretty much obligatory in my strict opinion.
