A little bit of a correction. It isn't sudden. Neither is it a purchase. Bhutan has been mining Bitcoin for half a decade now. Using hydropower, the small and happy country has been sustainably mining Bitcoin since 2019, back when the price per coin was still $5,000.
Yes, it's the 4th largest government holder of Bitcoin but it's unique in that its coins are earned organically, fresh, unlike the others whose coins are either seized from certain wallets or bought.
Wait, does that mean that some of the coins owned by some countries are seized assets? I actually had no idea about that
I actually thought they were all purchased by the government for future purposes or something like that
Well, I guess I've learnt something new today
The US had the most Bitcoin, hundreds of thousands, billions in USD, but it never invested in it. They seized billions worth of coins from Silk Road alone. China has billions in Bitcoin also, but it also didn't invest in it. They aren't even friendly with Bitcoin. Their coins are also confiscated from criminal activities. The same goes with Germany and the UK. They also had billions worth of Bitcoin, with Germany's coming mostly from piracy site Movie2k. Some of these countries' coins have already been sold or auctioned though.
